The opening as it read in October 6, 2023

Abd Allāh ibn Masʿūd ( ), c. 594 – c. 653 , was a companion of the Islamic prophet Muhammad whom Islamic tradition regards as the greatest interpreter of the Quran of his time and the second ever. He was also known by the kuniya Abu Abd al-Rahman . Abd Allah ibn Mas'ud was born in Mecca in about 594 a son of Masud ibn Ghafil and Umm Abd bint Abdwadd, both of whom were from the Hudhayl tribe, believed to be slaves, or otherwise of low social status. However, Umm Abd's mother, Hind bint Al-Harith, was from the Zuhra clan of the Quraysh , and Masud made an alliance with her brother. Abd Allah had a brother, Utba, and at least two wives in Muhammad's lifetime. One was Rayta bint Abd Allah, a craftswoman who supported Abd Allah and their child through her handcrafts. The other was Zaynab bint Abd Allah from the Thaqif tribe with whom he had several daughters. He specified in his will that none of his daughters should be married off without their own knowledge. He also had a son named Abd al-Rahman. He is described as a thin, short man with very dark skin, and smooth hair reaching to his shoulders. Abd Allah wore white clothes, and could be recognized in the dark by his distinctive, high-quality perfume. He was reported to be sociable and willing to speak out to put people at ease. In his character and goals, he was said to be the person "most like Muhammad". The Companions of Badr . (1990) Volume 15: The Crisis of the Early Caliphate . The Life of Muhammad .1
