Invocation for someone you have spoken ill to

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

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

(Allahumma fa-ayyuma mu/minin sababtuhu fajAAal thalika lahu qurbatan ilayka yawmal-qiyamah.)
