Hadith #3

3ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ كَانَ رَسُولُ الله (صلّى اللهُ عَلَيْهِ وَآلِه) إِذَا كَانَ فِي سَفَرٍ أَوْ عَجَّلَتْ بِهِ حَاجَةٌ يَجْمَعُ بَيْنَ الظُّهْرِ وَالْعَصْرِ وَبَيْنَ الْمَغْرِبِ وَالْعِشَاءِ قَالَ وَقَالَ أَبُو عَبْدِ الله (عَلَيْهِ الْسَّلام) لاَ بَأْسَ بِأَنْ تُعَجِّلَ عِشَاءَ الآخِرَةِ فِي السَّفَرِ قَبْلَ أَنْ يَغِيبَ الشَّفَقُ.

3. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Umayr from Hammad from al-Halabiy who has said the following: “This is a Hadith that abu ‘Abd Allah, ‘Alayhi al-Salam, has pronounced. ‘The Messenger of Allah, when on a journey or being in need for something, would perform al-Dhuhr and al-‘Asr Salah (prayer) together soon one after the other, as well as al-Maghrib and al-‘Isha’ Salah (prayer).’ He (the narrator) has said that abu ‘Abd Allah, ‘Alayhi al-Salam, has said, ‘It is not harmful to perform al-‘Isha’ al- Akhirah earlier on a journey and before the disappearance of brightness in the western horizon.’”
