The document summarizes the early life and missionary work of the prophet Muhammad in Makkah. It describes the religious landscape of Arabia at the time, with Zoroastrianism and Christianity being the dominant religions in the neighboring empires. Makkah practiced polytheism and idol worship. Muhammad began receiving divine revelations from God at age 40 and his first converts were his family members. After initial secret preaching, he publicly called the Makkans to monotheistic worship of Allah, meeting opposition from Abu Jahl and others. Many early Muslims suffered persecution but their numbers grew, including with the conversion of Umar ibn al-Khattab. Muhammad faced pressure to stop preaching but remained committed to restoring belief
