Sayyiduna Mus'ab ibn Umayr was the first ambassador of Islam, sent by the Prophet to Madinah before the Hijrah to teach the Ansar about Islam. Once the wealthiest and most fashionable young man of Makkah, he gave up all his luxuries for the sake of Islam. He was martyred at the Battle of Uhud while carrying the banner. His burial shroud was so short that his feet had to be covered with idhkhir grass.
