(81) باب الاِسْتِغْفَارِ بَعْدَ التَّسْلِيمِ
Thawban, the freed slave of the Messenger of Allah (ﷺ), narrated that:
When he finished the prayer, the Messenger of Allah (ﷺ) would pray for forgiveness three times and say: 'Allahumma anta asalam, wa minka as-salam tabarakta ya dhal-jalali wal-ikram (O Allah, You are the source of eace (or the One free from all faults) and from You comes peace, blessed are You, O Possessor of Majesty and Honor)."
