Mawlay Sulayman bin Mohammed (Arabic: سليمان بن محمد), born on 28 June 1766 in Tafilalt and died on 28 November 1822 in Marrakesh, was a Sultan of Morocco from 1792 to 1822, as a ruler of the 'Alawi dynasty.

[3] Mawlay Sulayman was born in Tafilalt on 28 June 1766[2] to Sidi Mohammed III and one of his wives a lady of the Ahlaf tribe.

[4] His father Sidi Mohammed took significant care in his religious education, thus Sulayman memorised the Qur'an in a Zawiya in Safi and studied the biography of Muhammad in Ksar al-Kabir.

In Marrakesh, he rebuilt the Ali bin Yusef Mosque, without leaving the slightest trace of its original Almoravid or Almohad design which dated from the early 12th century, completing its construction by 1819 or 1820.

[12] Mawlay Sulayman presented the United States with a two-storey mud and stone building in Tangier in 1821, the country's first acquired property.

The number of Makhzen troops assembled in Tadla amounted to 60,000 men, and in May 1819, Mawlay Sulayman headed to the Adekhsan where the Ait Umalu were raided, and the two sides engaged in a battle soon after.

Subsequently, Mawlay Sulayman headed north to inspect the forces besieging Tetuan and spent most of the winter directing military operations from Tangier.

[20] Despite receiving a reinforcement of 3,000 men from Dukkala who were mobilised by his nephew Mawlay Abd al-Rahman, the sultan failed to break the resistance of Tetuan, but succeeded in capturing the fortress of Martil in January 1822.

[23] During the reign of Mawlay Sulayman, the Wahhabi movement founded by Muhammad bin Abd al-Wahhab in the Arabian Peninsula reached Morocco.

[12] Mawlay Sulayman clearly opposed worshipping the so-called Muslim saints (ʾawliyāʾ ), and in 1805, he ordered the removal of a mausoleum in Rabat, where his father was buried, leaving only the grave.

[24] "An-Nâsiri said: The Sultan Al moulay Souleymân (ie Moulay Slimane), may Allah bless him, shared this point of view, which is why he wrote his book talking about the Sufis in which he warned against those who refute the Sunnah and support the innovation, as he explained the manner of visiting the Awliya (virtuous) and warned against the exaggeration of the lower people on it, and gave advice to the Muslims.
