The Istighfaar of Rasulullah Sallallahu alayhi wasallam
Ibn Umar (May Allah be pleased with them) said: We counted the Messenger of Allah saying
a hundred times during one single sitting:
رَبِّ اغْفِرْلِىْ وَ تُبْ عَلَىَّ اِنَّكَ اَنْتَ التَّوَّابُ الرَّحِيمْ
Rabbigh-firlee, wa tubb ‹alayya, innaka antat-Tawwaabur-Raheem.
My Rabb! Forgive me and pardon me. Indeed, You are the Oft-Returning with Compassion and Ever Merciful.
Abu Dawud and At- Tirmidhi.
