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`.
I exchanged some silver for gold with Talhah bin ‘Ubaidullah, and he said: Wait for me until our storekeeper comes from al-Ghabah, `Umar bin al-Khattab heard that and said: No, by Allah! Do not leave him until you take your exchange from him, for I heard the Messenger of Allah (ﷺ) say: `Gold for silver is riba unless it is `here, take this` and `here, take this` .”
Narrated It was narrated that 'Umar bin al-Khattab (رضي الله عنه) said:
The Messenger of Allah (ﷺ) shared out (some wealth) and I said, "By Allah, O Messenger of Allah, others deserved to have it more than these people." He said: "They gave me the choice of having them ask importunately or regard me as a miser, and I am not a
miser."
