Remembrance 7 from Chapter 51
What to say in the morning and the evening
Allāhumma Anta Rabbī, lā ilāha illā Ant, khalaqtanī wa anā ‘abduk, wa anā ‘alā ‘ahdika wa wa‘dika mā’staṭa‘t, a‘ūdhu bika min sharri mā ṣana‘t, abū’u laka bi-ni‘matika ‘alayya wa abū’u laka bi-dhambī, fa-ghfir lī, fa-innahu lā yaghfiru-dh-dhunūba illā Ant.
We relate in the Ṣaḥīḥ of al-Bukhārī from Shaddād ibn Aws 
, from the Prophet 
who said: “The chief formula for seeking forgiveness is: O Allah, You are my Lord; there is no god but You. You created me and I am Your slave; and I am under Your covenant and pledge [to fulfil it] to the best of my ability. I seek Your protection from the evil that I have done, acknowledging Your favour on me and admitting my sin. So forgive me, for none forgives sins but You. Whoever says it during the day and then passes away before the evening will be one of the people of Paradise. And whoever says it during the night and then passes away before the morning will be one of the people of Paradise.” [7].The meaning of ‘I return’ (abū’u) is ‘I affirm or ‘I acknowledge’.
