[1][2] A khatib, and qāriʾ, he previously led Taraweeh and Tahajjud prayers at Masjid al-Haram starting in the year 2015[3][4] and also served as the imam of several mosques in Riyadh since 1995.

Al-Dawsari was a student of a group of 'ulama and sheikhs, including Abd al-Aziz Al al-Shaykh, Salih al-Fawzan, and Ibn Jibrin.

[6] Near the end of 2023, his four-year contract as imam expired, and he did not lead prayers at Masjid al-Haram for about five and a half months.

On 29 Sha'ban 1436 H (15 June 2015), King Salman bin Abdulaziz issued an order for Al-Dawsari to become one of the Imams of Taraweeh and Tahajjud at Masjid Al-Haram during Ramadan.

He was appointed for that position after Abdul-Rahman Al-Sudais, Head of the General Presidency of Haramain, decided to reorganize the ranks of the advisory body of that government agency.
