Ibraheem at-Tamimi once said:
"When a man wrongs me, I pay him back with an act of mercy."
When some money was stolen from a righteous man who lived in Khurasaan, he began to weep. Fu'dayl, who saw him in that state, asked, "Why do you cry?" He answered, "I remembered that Allah
shall gather me and the thief together on the Day of Judgment, and I cried, feeling pity for him."
A man slandered a scholar from the early generations of Islam.
In return, the scholar gave him a gift of dates, and when later asked about the gifts, he said,
"Because he did good to me (i.e. on the Day of Judgment the man would have to give him some of his good deeds or take from him some of his bad ones)."
