Invocation for someone you have spoken ill to

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

Qāla an-nabiyyu ṣallallāhu ʿalayhi wa sallam: ((allāhumma fa-ayyumā muʾminin sababtuhu fajʿal dhalika lahu qurbatan ilayka yawma al-qiyāmati)).

(O Allah, to any believer whom I have insulted, let that be cause to draw him near to You on the Day of Resurrection.)
