Muhammad bin Abdulaziz (Arabic: محمد بن عبد العزيز ال سعود) was a member of the royal family.
He was among the wealthiest and most powerful members of the Saudi royal family. His advise was sought and deferred to in all matters by his brothers. Until his death in 1988, he was a close and powerful confidant and senior adviser to his younger brothers, King Khalid and King Fahd.
Prince Muhammad was born in 1910 and is the fourth son of the Kingdom's founder, King Abdulaziz. King Khalid was his full brother. Their mother was from the important Al Jiluwis, a clan whose members intermarried with the members of Al Saud family, Al Jawharah bint Musaed bin Jalawi. She hired the best Najdi horse riders to train cavalry who in turn contributed significantly in King AbdulAziz's attempts to unify Saudi Arabia.
Prince Muhammed's and also, King Khalid's mother was special for King Abdulaziz due to several reasons. First, Jawharah al Jiluwi was King Abdulaziz's cousin. Secondly, she was chosen by King Abdulaziz's mother as a wife for him. And lastly, she died at a young age.
