Sunan Abu Dawood 1515
Al-Agharr al-Muzani said (Musaddad in his version of this tradition said that he was a Companion of the Prophet):
The Messenger of Allah ﷺ said: My heart is invaded by unmindfulness, and I ask Allah's pardon a hundred times in the day.
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، وَمُسَدَّدٌ، قَالاَ حَدَّثَنَا حَمَّادٌ، عَنْ ثَابِتٍ، عَنْ أَبِي بُرْدَةَ، عَنِ الأَغَرِّ الْمُزَنِيِّ، - قَالَ مُسَدَّدٌ فِي حَدِيثِهِ وَكَانَتْ لَهُ صُحْبَةٌ - قَالَ قَالَ رَسُولُ اللَّهِ ﷺ
" إِنَّهُ لَيُغَانُ عَلَى قَلْبِي وَإِنِّي لأَسْتَغْفِرُ اللَّهَ فِي كُلِّ يَوْمٍ مِائَةَ مَرَّةٍ " .
