ʻAmmār ibn Yāsir ibn ʿĀmir ibn Mālik Abū al-Yaqzān (Arabic: عمار ابن یاسر‎‎) was one of the Muhajirun in the history of Islam and, for his dedicated devotion to Islam's cause, is considered to be one of the most loyal and beloved companions of Muhammad and ‘Ali; thus, he occupies a position of the highest prominence in Islam. Historically, Ammar ibn Yasir is the first Muslim to build a mosque. He is also referred to by Shia Muslims as one of the Four Companions. Ammar's ultimate fate was unique than the fate of the rest of Mohammad's companions, for his martyrdom in the battle of Siffin decisively distinguished the righteous group from the sinful one in the First Fitna.

ʻAmmar belonged to Banu Makhzum tribe in Hijaz (current-day Saudi Arabia). He was born in the Year of the Elephant, which was the same year as Muhammad's birth, in Mecca and was one of the intermediaries in the Muhammad's marriage to Khadijah bint Khuwaylid. His father, Yasir ibn Amir, was from the tribe of Qahtan in Yemen and migrated to Mecca and settled down there by marrying Sumayyah bint Khayyat, a slave woman; Ammar and his parents, Yasir and Sumayyah, were slaves to Abu Huzaifa, but upon his death, Abu Jahl -who became later one of Islam's most brutal enemies and the infamous torturer of Ammar and his parents- took them over as his slaves. Ammar's trust in and knowledge of Muhammad's credibility, even before his prophethood, encouraged him to follow Muhammad's prophetic visions as one of the earliest converts.
