Supplication for One You Have Insulted

قَالَ النَّبِيُّ صلى الله عليه وسلم: ((اللَّهُمَّ فَأَيُّمَا مُؤْمِنٍ سَبَبْتُهُ فَاجْعَلْ ذَلِكَ لَهُ قُرْبَةً إِلَيْكَ يَوْمَ الْقِيَامَةِ)).

The Prophet (peace and blessings of Allah be upon him) said: "O Allah, whichever believer I have cursed, make that a means of nearness for him to You on the Day of Resurrection."
