'Abd Allah b. 'Umar

Ya'la ibn Umayyah, may Allah be pleased with him, was a companion of the Prophet Muhammad ﷺ who participated in several military campaigns including the expedition of Tabuk. He is primarily known in the hadith literature for his narrations concerning the rites of Hajj and Umra — particularly the rules that apply to pilgrims in the state of ihram (sacred state of pilgrimage). He narrated an important hadith regarding the permissibility of wearing a cloak sewn with saffron-colored dye and the subsequent ruling on what a pilgrim in ihram must do when wearing it. This narration, preserved in Sahih al-Bukhari and Sahih Muslim, is among the most cited in classical fiqh works on the rites of Hajj. He is also associated with narrations on matters of financial transactions and prophetic conduct. He settled in Kufa or Syria after the Prophet's death. His narrations, though limited in number, carry high weight in Islamic jurisprudence, particularly on questions of Hajj, and they appear in the Sahihayn and the major Sunan collections.
