Chapter 26: Selling Sadaqa and Taking it Back
Muwatta Malik 643
Yahya related to me from Malik from Nafi from Abdullah ibn Umar that Umar ibn al-Khattab gave a horse to carry someone in the way of Allah, and then he wished to buy it back. So he asked the Messenger of Allah ﷺ about it, and he said, "Do not buy or take back your sadaqa."
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، حَمَلَ عَلَى فَرَسٍ فِي سَبِيلِ اللَّهِ فَأَرَادَ أَنْ يَبْتَاعَهُ فَسَأَلَ عَنْ ذَلِكَ رَسُولَ اللَّهِ صلى الله عليه وسلم فَقَالَ
" لاَ تَبْتَعْهُ وَلاَ تَعُدْ فِي صَدَقَتِكَ " .
