He was born an orphan, cared for by Abd al-Muttalib then Abu Talib. He was known as the truthful and trustworthy before revelation. He married Khadijah, and Jibril came to him in the cave of Hira.
He called in secret then in public, endured harm for thirteen years in Makkah, then migrated. In Madinah the mosque was built, the constitution written, and he struggled until the opening of Makkah in year 8, the Farewell Hajj in year 10, and he joined the Highest Companion in Rabi' al-Awwal of year 11.
There is no prophet after him. Whoever claims prophethood after him has denied the Quran: he is the Messenger of Allah and the seal of the prophets.
