Ibn "Umar saw Sa"d bin Malik wiping over his leather slippers. Ibn ʼUmar said: Is it you doing this? Sa"d said: Yes. They both went to ‘Umar and Sa"d said to ‘Umar, Give my brother"s son a fatwa with regard to wiping over leather slippers. "Umar said, When we were with our Prophet (ﷺ) we used to wipe over our leather slippers. Ibn "Umar said: Even if that is after one has defecated and urinated? He said: Yes, even if that is after one has defecated and urinated. Nafiʼ said: After that, Ibn ‘Umar would wipe over them and not take them off, and he did not give a time limit for that. I told that to Ma"mar and he said: Ayyoob told me something similar from Nafi".
