2ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ أَحْمَدَ بْنِ النَّضْرِ الْخَزَّازِ عَنْ عَمْرِو بْنِ شِمْرٍ عَنْ جَابِرٍ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ السَّلاَم) قَالَ قَالَ رَسُولُ الله (صلَّى اللهُ عَلَيْهِ وَآلِه) لِجَابِرِ بْنِ عَبْدِ الله يَا جَابِرُ هَذَا شَهْرُ رَمَضَانَ مَنْ صَامَ نَهَارَهُ وَقَامَ وِرْداً مِنْ لَيْلِهِ وَعَفَّ بَطْنُهُ وَفَرْجُهُ وَكَفَّ لِسَانَهُ خَرَجَ مِنْ ذُنُوبِهِ كَخُرُوجِهِ مِنَ الشَّهْرِ فَقَالَ جَابِرٌ يَا رَسُولَ الله مَا أَحْسَنَ هَذَا الْحَدِيثَ فَقَالَ رَسُولُ الله (صلَّى اللهُ عَلَيْهِ وَآلِه) يَا جَابِرُ وَمَا أَشَدَّ هَذِهِ الشُّرُوطَ.

2. Ali ibn Ibrahim has narrated from his father from Ahmad ibn al-Nadr al-Khazzaz from ‘Amr ibn Shamir from Jabir who has said the following: “Abu Ja’far, ‘Alayhi al-Salam, has said, ‘The Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, once said to Jabir ibn ‘Abd Allah, “O Jabir, this is the month of Ramadan. Anyone who fasts during its days, stands for salat (prayer) during its nights, maintains his stomach and private parts chastely and controls his tongue, comes out of his sins just like his coming out of the month.” Jabir then said, “How beautiful is this Hadith, O the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause.” The Messenger of Allah said, “O Jabir, how strict these conditions are!”’”
