Musannaf Ibn Abi Shaybah

Hazrat Abdur Rahman bin Abzi narrates that when the Messenger of Allah (peace and blessings be upon him) would enter the morning, he would recite this supplication: Translation: We have entered the morning upon the nature of Islam and the word of sincerity, and upon the religion of our Prophet Muhammad (peace and blessings be upon him), and upon the way of our father Ibrahim, who was a true Muslim and was not among the polytheists.
