It is not known the year in which Mashaan was born, and none of his collectors mention this except Talal Al-Saeed, who said that he was born in 1209 AH about 1209 hijri, and did not mention his reference. But Mashaan's father Mughliath was killed in 1238 AH in the sense that he was able to fight, and Mashaan was killed two years later. His mother was alive at that time, which urged him to avenge his father.
