Musannaf Ibn Abi Shaybah

Hazrat Abdur Rahman bin Abzi narrates that when the morning would come, the Messenger of Allah (peace and blessings be upon him) would supplicate: We have entered the morning upon the nature of Islam, and upon the word filled with sincerity, and upon the religion of our Prophet Muhammad (peace and blessings be upon him), and upon the pure faith of our father Ibrahim, and he was not among the polytheists.
