Dua for Laylat-ul-Qadr
Aishah (Radhi Allah Anha) asked Prophet Muhammad (Sal Allahu Alayhi Wa Sallam), “If I know which night is Laylat-ul-Qadr what should I supplicate in it?”
He (Sal Allahu Alayhi Wa Sallam) said, “Say:
اَللّٰهُمَّ اِنَّكَ عَفُوٌّ تُحِبُّ الْعَفْوَ فَاعْفُ عَنِّيْ
Allahumma innaka 'afuwwun tuhibbul 'afwa fa'fu 'anni
O Allah, You are Most Forgiving and You love forgiveness, so forgive me.
