(30) باب فَضَائِلِ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ رضى الله عنهما
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:
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.
