حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، ‏.‏ أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ قَالَ ‏"‏ لَوْلاَ أَنْ أَشُقَّ عَلَى أُمَّتِي لأَمَرْتُهُمْ بِتَأْخِيرِ الْعِشَاءِ ‏"‏ ‏.‏

It was narrated from Abu Hurairah that: The Messenger of Allah said: "Were it not that it would be too difficult for my Ummah, I would have commanded them to delay the 'Isha'." Translation Not Available
