Muhammad bin Salih Al-Uthaymin (Arabic: محمد بن صالح العثيمين, romanized: Muḥammad ibn Ṣāliḥ; 9 March 1929 – 10 January 2001), commonly known by his laqab Al-Uthaymin (Arabic: العثيمين, romanized: al-ʿUthaymīn), was a Saudi Islamic scholar.

His ancestor Ahmad bin Muqbil Al-Tamimi was from the Wahabah sub-tribe of the Banu Tamim.

Muhammad bin Sulayman thus went on to enquire about the meaning of this dream from scholars who were skilled in the realm of dream interpretation, these scholars then told him that he would have a child who would be salih, meaning pious and would have an elevated position when it comes to the knowledge of the religion.

[10][11] After completing his memorization of the Qur'an and foundational studies, he began his full-time religious studies under Sheikhs Muhammad ibn 'Abd al-'Aziz al-Mutawwa' and Ali al-Salihi in Unayzah, the two teachers that sheikh 'Abd al-Rahman al-Sa'di had appointed to instruct beginning students.

The year 1952, al-Salihi advised al-Uthaymeen to enroll in the newly opened Ma'had al-'Ilmi in Riyadh, which he did after seeking permission from al-Sa'di.
