Sahih Muslim 2477
Sahih Muslim · Book 44: The Book of the Merits of the Companions · The Virtues Of 'Abdullah Bin 'Abbas (RA)
Ibn 'Abbas reported that Allah's Messenger (ﷺ) came to privy and I placed for him water for ablution, When he came out he said:
حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ ، وَأَبُو بَكْرِ بْنُ النَّضْرِ قَالاَ حَدَّثَنَا هَاشِمُ بْنُ الْقَاسِمِ ، حَدَّثَنَا وَرْقَاءُ بْنُ عُمَرَ الْيَشْكُرِيُّ ، قَالَ سَمِعْتُ عُبَيْدَ اللَّهِ بْنَ أَبِي يَزِيدَ ، يُحَدِّثُ عَنِ ابْنِ عَبَّاسٍ ، أَنَّوسلم أَتَى الْخَلاَءَ فَوَضَعْتُ لَهُ وَضُوءًا فَلَمَّا خَرَجَ قَالَ " مَنْ وَضَعَ هَذَا " . فِي رِوَايَةِ زُهَيْرٍ قَالُوا . وَفِي رِوَايَةِ أَبِي بَكْرٍ قُلْتُ ابْنُ عَبَّاسٍ . قَالَ " اللَّهُمَّ فَقِّهْهُ " .
Who placed it here? And in a version of Zuhair they (the Companions) said, and in the version of Abu Bakr (the words are): I said: It is Ibn 'Abbas (who has done that), whereupon he (the Holy Prophet) said: May Allah grant him deep understanding of religion.
