The Prophet (sallallaahu ’alayhi wa sallam) is reported to have said on the authority of Umar (RA) that “when Adam committed his mistake he said: O Lord, I am asking you to forgive me for the sake of Muhammad. Allaah said: O Adam, and how do you know of Muhammad whom I have not yet created? Adam replied: O my Lord, after you created me with Your Hand and breathed into me of Your spirit, I raised my head and saw written on the heights of the Throne, ‘none has the right to be worshipped save Allaah and Muhammad is the Messenger of
Allaah.’ I understood that You would not place next to Your Name but the most beloved one of your creation. Allaah said: O Adam, I have forgiven you and were it not for Muhammad I would not have created you.”

This hadeeth was reported by AlHakem in His Mustad’rak.
Sheikh Al Albani graded it as fabricated and a lie.
