أَسْتَغْفِرُ اللَّهَ وَأَتُوبُ إِلَيْهِ
Astaghfirullaha wa atubu ilayh
I seek Allah's forgiveness and I repent to Him. (The Prophet ﷺ used to say this more than 100 times a day.)
Al-Agharr al-Muzani (RA) narrated that the Prophet ﷺ used to seek Allah's forgiveness more than 100 times in a single day. Despite being forgiven all his past and future sins, he ﷺ maintained this practice out of gratitude and humility.
