to King Saud's Al Naṣariah Palace in Fall 1964 to demand his and his sons' loyalty to the chosen king, Faisal. On 28 November 1964 Radio Mecca announced the allegiance of eleven of Saud's sons to King Faisal. Royal advisor Muhammad bin Abdulaziz was Crown Prince during the first few months (November 1964 – March 1965) of the reign of King Faisal. He then voluntarily stepped aside from the succession to allow his younger and only full brother, Prince Khalid, to become heir apparent to the Saudi throne. However, it is argued by Ayman Al Yassini that it was not a voluntarily move and that Prince Muhammad was forced to step aside from the succession by the senior members of the Al Saud family and the ulema due to his personal characteristics which were considered not to be proper for Wahhabism. Prince Muhammad's nickname was Abu Sharayn or "the father of two evils" referring to his bad temper and his habit of drinking.

In addition, Prince Muhammad was a frequent visitor to the parties in Beirut which he himself did not consider a proper act for a royal. All such traits were the reasons for not being selected as the king by his brothers. It is also argued that Prince Muhammad, the oldest surviving son of King Abdulaziz after Faisal, either declined the role of crown prince or was passed over because of his close association with King Saud during the latter's reign.

After the death of King Khalid on 13 June 1982, the royal family council led by Prince Muhammad expressed its allegiance to the new king, Fahd. Prince Muhammad died on 25 November 1988 at approximately 78 years of age and was buried in Riyadh. Controversy Prince Muhammad's granddaughter, Misha'al bint Fahd, was convicted
