Arabic (Original)
حَدَّثَنَا وَكِيعٌ حَدَّثَنَا عَمْرُو بْنُ عُثْمَانَ عَنْ مُوسَى بْنِ طَلْحَةَ عَنْ عُثْمَانَ بْنِ أَبِي الْعَاصِ قَالَ قَالَ لِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَا عُثْمَانُ أُمَّ قَوْمَكَ وَمَنْ أَمَّ الْقَوْمَ فَلْيُخَفِّفْ فَإِنَّ فِيهِمْ الضَّعِيفَ وَالْكَبِيرَ وَذَا الْحَاجَةِ فَإِذَا صَلَّيْتَ لِنَفْسِكَ فَصَلِّ كَيْفَ شِئْتَ.
English Translation
Waki' told us: 'Amr ibn 'Uthman told us, from Musa ibn Talhah, from 'Uthman ibn Abi al-'As, who said: The Messenger of Allah, peace and blessings be upon him, said to me: O 'Uthman, lead your people in prayer, and whoever leads people in prayer should be brief, for among them are the weak, the elderly, and those with pressing needs; but when you pray for yourself, pray as long as you wish.
