حَدَّثَنَا حُسَيْنُ بْنُ مُحَمَّدٍ حَدَّثَنَا شَرِيكٌ عَنْ عَبْدِ اللَّهِ بْنِ عُصْمٍ عَنِ ابْنِ عَبَّاسٍ يَقُولُ أُمِرَ نَبِيُّكُمْ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِخَمْسِينَ صَلَاةً فَسَأَلَ رَبَّهُ عَزَّ وَجَلَّ فَجَعَلَهَا خَمْسَ صَلَوَاتٍ
مسند امام احمد بن حنبل · Hadith 2892
It was narrated that 'Abdullah bin 'Usm said: I heard Ibn 'Abbas (RA) say; Your Prophet (PBUH) was enjoined to offer fifty prayers, then he asked his Lord, may He be glorified and exalted, and He made them five prayers.
