1ـ الْحُسَيْنُ بْنُ مُحَمَّدٍ الأشْعَرِيُّ عَنْ عَبْدِ الله بْنِ عَامِرٍ عَنْ عَلِيِّ بْنِ مَهْزِيَارَ عَنْ فَضَالَةَ بْنِ أَيُّوبَ عَنِ الْحُسَيْنِ بْنِ عُثْمَانَ عَنِ ابْنِ مُسْكَانَ عَنْ زُرَارَةَ قَالَ قَالَ لِي أَ تَدْرِي لِمَ جُعِلَ الذِّرَاعُ وَالذِّرَاعَانِ قَالَ قُلْتُ لِمَ قَالَ لِمَكَانِ الْفَرِيضَةِ لَكَ أَنْ تَتَنَفَّلَ مِنْ زَوَالِ الشَّمْسِ إِلَى أَنْ يَبْلُغَ ذِرَاعاً فَإِذَا بَلَغَ ذِرَاعاً بَدَأْتَ بِالْفَرِيضَةِ وَتَرَكْتَ النَّافِلَةَ.

1. Al-Husayn ibn Muhammad al-Ash’ariy has narrated from ‘Abd Allah ibn ‘Amir from Ali ibn Mahziyar from Fadalah ibn Ayyub from al-Husayn ibn ‘Uthman from ibn Muskan from Zurarah who has said the following: “He (the Imam), ‘Alayhi al-Salam, once said to me, ‘Do you know why one and two yards are set?’ I (the narrator) said, ‘Why are they set?’ He (the Imam) said, ‘It is because of obligatory Salah (prayer). You can perform optional Salah (prayer) soon after the sun declines (to the west at noontime) until it become one yard, but if you begin the obligatory one, you do not perform optional Salah (prayer).”’

2ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ فَضَّالٍ عَنْ يُونُسَ بْنِ يَعْقُوبَ عَنْ مِنْهَالٍ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) عَنِ الْوَقْتِ الَّذِي لاَ يَنْبَغِي لِي [أَنْ يَتَنَفَّلَ‏] إِذَا جَاءَ الزَّوَالُ قَالَ ذِرَاعٌ إِلَى مِثْلِهِ.

2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Faddal Yunus ibn Ya‘qub from Minhal who has said the following: “I once asked abu ‘Abd Allah, ‘Alayhi al-Salam, about the time when I should not perform any optional Salah (prayer) after the sun declines toward the west at noontime. He (the Imam) replied, ‘When it is one yard until it is like it (twice as much).”’

3ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ سَمَاعَةَ قَالَ سَأَلْتُهُ عَنِ الرَّجُلِ يَأْتِي الْمَسْجِدَ وَقَدْ صَلَّى أَهْلُهُ أَ يَبْتَدِئُ بِالْمَكْتُوبَةِ أَوْ يَتَطَوَّعُ فَقَالَ إِنْ كَانَ فِي وَقْتٍ حَسَنٍ فَلاَ بَأْسَ بِالتَّطَوُّعِ قَبْلَ الْفَرِيضَةِ وَإِنْ كَانَ خَافَ الْفَوْتَ مِنْ أَجْلِ مَا مَضَى مِنَ الْوَقْتِ فَلْيَبْدَأْ بِالْفَرِيضَةِ وَهُوَ حَقُّ الله عَزَّ وَجَلَّ ثُمَّ لْيَتَطَوَّعْ بِمَا شَاءَ أَلاَ هُوَ مُوَسَّعٌ أَنْ يُصَلِّيَ الإِنْسَانُ فِي أَوَّلِ دُخُولِ وَقْتِ الْفَرِيضَةِ النَّوَافِلَ إِلاَّ أَنْ يَخَافَ فَوْتَ الْفَرِيضَةِ وَالْفَضْلُ إِذَا صَلَّى الإِنْسَانُ وَحْدَهُ أَنْ يَبْدَأَ بِالْفَرِيضَةِ إِذَا دَخَلَ وَقْتُهَا لِيَكُونَ فَضْلُ أَوَّلِ الْوَقْتِ لِلْفَرِيضَةِ وَلَيْسَ بِمَحْظُورٍ عَلَيْهِ أَنْ يُصَلِّيَ النَّوَافِلَ مِنْ أَوَّلِ الْوَقْتِ إِلَى قَرِيبٍ مِنْ آخِرِ الْوَقْتِ.

3. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from ‘Uthman ibn ‘Isa from Sama‘ah who has said the following: “I once asked him (the Imam), ‘Alayhi al-Salam, about a man who comes to Masjid when people there have completed their Salah (prayer). Should he begin the obligatory or optional before the obligatory? He (the Imam) said, ‘If it is a good time it is not harmful to perform optional Salah (prayer) before obligatory. If he fears that time may end, he must begin the obligatory, which is the right of Allah, most Majestic, most Glorious, then perform optional Salah (prayer) whatever he wants. The time for optional Salah (prayer) is longer. One can perform in the beginning of the time for obligatory optional ones, unless one is afraid of passing of the time of obligatory one. It is better when one performs alone to begin with obligatory, if it is time for it, so that it is performed during the excellent time which is in the beginning of time. It is not prohibited to perform optional Salah (prayer) at the beginning of time up to near the end of the time.’”

4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from ‘Uthman ibn ‘Isa from Ishaq ibn ‘Ammar who has said the following: “I once asked him (the Imam), ‘Alayhi al-Salam, ‘Can I perform optional Salah (prayer) in the time for obligatory one?’ He (the Imam) replied, ‘Yes, you can do so in the beginning of time if you are with the Imam who leads you in Salah (prayer). If you are alone, then perform the obligatory first.’”

5. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Umayr from abu Ayyub from Muhammad ibn Muslim who has said the following: “I once said to abu ‘Abd Allah, ‘Alayhi al-Salam, ‘When the time for obligatory Salah (prayer) comes, should I perform optional Salah (prayer) or begin the obligatory one?’ He (the Imam) said, ‘It is better to begin with obligatory. Al-Dhuhr is delayed to one yard from Zawal (declining of the sun toward the west at noontime) by one yard for Salah (prayer) of repentant people.’”

6ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ أَبِي أَيُّوبَ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ قَالَ قُلْتُ لأَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) إِذَا دَخَلَ وَقْتُ الْفَرِيضَةِ أَتَنَفَّلُ أَوْ أَبْدَأُ بِالْفَرِيضَةِ قَالَ إِنَّ الْفَضْلَ أَنْ تَبْدَأَ بِالْفَرِيضَةِ.

6. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Umayr from abu Ayyub from Muhammad ibn Muslim who has said the following: “I once asked abu ’Abd Allah, ‘Alayhi al-Salam, ‘When the time for obligatory Salah (prayer) comes, can I perform optional Salah (prayer) or begin with obligatory Salah (prayer)?’ He (the Imam) replied, ‘It is better to begin with the obligatory Salah (prayer).”’

7ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ عُمَرَ بْنِ أُذَيْنَةَ عَنْ عِدَّةٍ مِنْ أَصْحَابِنَا أَنَّهُمْ سَمِعُوا أَبَا جَعْفَرٍ (عَلَيْهِ الْسَّلام) يَقُولُ كَانَ أَمِيرُ الْمُؤْمِنِينَ (صلّى اللهُ عَلَيْهِ وَآلِه) لاَ يُصَلِّي مِنَ النَّهَارِ حَتَّى تَزُولَ الشَّمْسُ وَلاَ مِنَ اللَّيْلِ بَعْدَ مَا يُصَلِّي الْعِشَاءَ الآخِرَةَ حَتَّى يَنْتَصِفَ اللَّيْلُ. مَعْنَى هَذَا أَنَّهُ لَيْسَ وَقْتَ صَلاَةِ فَرِيضَةٍ وَلاَ سُنَّةٍ لأَنَّ الأوْقَاتَ كُلَّهَا قَدْ بَيَّنَهَا رَسُولُ الله (صلّى اللهُ عَلَيْهِ وَآلِه) فَأَمَّا الْقَضَاءُ قَضَاءُ الْفَرِيضَةِ وَتَقْدِيمُ النَّوَافِلِ وَتَأْخِيرُهَا فَلاَ بَأْسَ.

7. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Umayr from ‘Umar ibn ’Udhaynah from a number of our people who has said the following: “They had heard abu Ja‘far, ‘Alayhi al-Salam, say, ‘’Amir al-Mu’minin, ‘Alayhi al-Salam, would not perform Salah (prayer) during the day until Zawal (declining of the sun toward the west at noontime). During the night he would not perform any Salah (prayer) after al-‘Isha’ up until midnight. It means that it is not time for obligatory or optional Salah (prayer); the Messenger of Allah has defined all times. However, to perform a make-up for obligatory or performing optional Salah (prayer) before or after is not harmful.’”

8ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ رَفَعَهُ قَالَ قَالَ رَجُلٌ لأَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) الْحَدِيثُ الَّذِي رُوِيَ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ الْسَّلام) أَنَّ الشَّمْسَ تَطْلُعُ بَيْنَ قَرْنَيِ الشَّيْطَانِ قَالَ نَعَمْ إِنَّ إِبْلِيسَ اتَّخَذَ عَرْشاً بَيْنَ السَّمَاءِ وَالأرْضِ فَإِذَا طَلَعَتِ الشَّمْسُ وَسَجَدَ فِي ذَلِكَ الْوَقْتِ النَّاسُ قَالَ إِبْلِيسُ لِشَيَاطِينِهِ إِنَّ بَنِي آدَمَ يُصَلُّونَ لِي.

8. Ali ibn Ibrahim has narrated from his father from in a marfu‘ manner the following; “Once a man mentioned before abu ‘Abd Allah, ‘Alayhi al-Salam, the Hadith which is narrated from abu Ja‘far, ‘Alayhi al-Salam, that says, ‘The sun emerges from between the two horns of Satan.’ He (the Imam) said, ‘Yes, Iblis has found a throne between the sky and earth. When the sun rises and people prostrate at that time, Iblis then says to his other Satans, ‘Children of Adam perform Salah (prayer) for me.’”

9ـ عَلِيُّ بْنُ مُحَمَّدٍ عَنْ سَهْلِ بْنِ زِيَادٍ عَنِ الْحُسَيْنِ بْنِ رَاشِدٍ عَنِ الْحُسَيْنِ بْنِ أَسْلَمَ قَالَ قُلْتُ لأَبِي الْحَسَنِ الثَّانِي (عَلَيْهِ الْسَّلام) أَكُونُ فِي السُّوقِ فَأَعْرِفُ الْوَقْتَ وَيَضِيقُ عَلَيَّ أَنْ أَدْخُلَ فَأُصَلِّيَ قَالَ إِنَّ الشَّيْطَانَ يُقَارِنُ الشَّمْسَ فِي ثَلاَثَةِ أَحْوَالٍ إِذَا ذَرَّتْ وَإِذَا كَبَّدَتْ وَإِذَا غَرَبَتْ فَصَلِّ بَعْدَ الزَّوَالِ فَإِنَّ الشَّيْطَانَ يُرِيدُ أَنْ يُوقِعَكَ عَلَى حَدٍّ يُقْطَعُ بِكَ دُونَهُ.

9. Ali ibn Muhammad has narrated from Sahl ibn Ziyad from al-Husayn ibn Rashid from al-Husayn ibn Aslama who has said the following: “I once said to abu al-Hassan al-Thaniy, ‘Alayhi al-Salam, ‘In the market place I come to know that it is time but it becomes difficult (to perform Salah (prayer)) after I enter the market place (for business).’ He (the Imam) said, ‘Satan nears the sun during three conditions, at sunrise, Zawal (declining of the sun toward the west at noontime) and at sunset. You must perform Salah (prayer) after Zawal (declining of the sun toward the west at noontime); Satan wants to mislead you from the right path.’”
