It Is Disliked For A Man To Buy What He Gave In Charity From The One To Whom He Gave It
وَحَدَّثَنِيهِ زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ، - يَعْنِي ابْنَ مَهْدِيٍّ - عَنْ مَالِكِ، بْنِ أَنَسٍ بِهَذَا الإِسْنَادِ وَزَادَ " لاَ تَبْتَعْهُ وَإِنْ أَعْطَاكَهُ بِدِرْهَمٍ " .
This hadith has been narrated on the authority of Malik b. Anas with the same chain of transmitters but with this addition:" Don't buy that even if he gives you for one dirham."
