Mus'ab ibn 'Umayr was the cherished son of a wealthy Makkan family, known for fine clothes and perfume. When he accepted Islam his family cut him off from every comfort, yet he did not give up his faith.
After the first pledge of 'Aqabah, the Messenger of Allah ﷺ sent him to Madinah to teach people the Quran. Through his patience and gentle calling many households of Madinah believed, and a city was made ready for the Hijrah.
❝ HadithKhabbab said: we emigrated with the Messenger of Allah ﷺ seeking Allah's pleasure. Some of us passed away without taking any of their reward in this world — among them Mus'ab ibn 'Umayr. He was martyred at Uhud, and nothing could be found to shroud him but one sheet. If his head was covered his feet showed, and if his feet were covered his head showed. The Messenger of Allah ﷺ said: cover his head and put idhkhir grass over his feet.Sahih al-Bukhari 1276 · Sahih
