Al-Nawawi said, “It is said that it means the Prophet had intervals of distraction from the remembrance of Allah, as remembrance was his normal state of affairs. When he had a period of inattention or unmindfulness, he would consider that a sin and seek forgiveness for it.”

عَنْ الْأَغَرِّ الْمُزَنِيِّ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِنَّهُ لَيُغَانُ عَلَى قَلْبِي وَإِنِّي لَأَسْتَغْفِرُ اللَّهَ فِي الْيَوْمِ مِائَةَ مَرَّةٍ
