Abu Hurairah reported,

The Prophet ﷺ said, "O Allah, this is Your servant and the son of Your servant. He used to bear witness that there is no god but You, and that Muhammad is Your servant and Messenger, and You know him best. If he was a doer of good, then increase him in his goodness, and if he was a wrongdoer, then forgive him. Do not deprive us of his reward, and do not lead us astray after him."

عن أبي هريرة

عن النبي ﷺ قال: اللهم عبدك وابن عبدك، كان يشهد أن لا إله إلا أنت، وأن محمدا عبدك ورسولك، وأنت أعلم به، إن كان محسنا فزده في إحسانه، وإن كان مسيئا فاغفر له، ولا تحرمنا أجره ولا تفتنا بعده.
