It is narrated from a Companion (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: O people! Keep repenting to your Lord, and I myself repent to Him a hundred times in a day. I asked him, "Are 'Allahumma inni astaghfiruka' and 'Allahumma inni atubu ilaik' two separate things or the same?" The Noble Prophet (peace and blessings be upon him) said: They are the same.
