Thauban (May Allah be pleased with him) reported:
Whenever the Messenger of Allah
he would beg forgiveness from Allah thrice and then would recite:
"Allahumma Antas-Salamu, wa minkas-salamu, tabarakta ya Dhal-Jalali wal-Ikram
(O Allah, You are the Grantor of security, and security comes from You.
You are Blessing, O You Who have majesty and nobility)!''
(Imam) Al-Awza`i, one of the narrators of this Hadith, was asked:
"How forgiveness is to be sought?''
(I beseech Allah for forgiveness, I beseech Allah for forgiveness)'.''
