حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ وَحَجَّاجٌ قَالَا حَدَّثَنَا شُعْبَةُ سَمِعْتُ أَبَا إِسْحَاقَ وَقَالَ حَجَّاجٌ فِي حَدِيثِهِ عَنْ أَبِي إِسْحَاقَ سَمِعْتُ يَحْيَى بْنَ وَثَّابٍ أَنَّهُ سَأَلَ ابْنَ عُمَرَ عَنْ الْغُسْلِ يَوْمَ الْجُمُعَةِ فَقَالَ أَمَرَنَا بِهِ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ
مسند امام احمد بن حنبل · Hadith 5128
It was narrated from Abu ishaaq: I heard Yahya Ibn Waththaab (say) that he asked Ibn 'Umar about doing ghusl on Friday and he said: The Messenger of Allah (PBUH) instructed us to do it.
