Abu al-Bara' Amir ibn Malik

Abū al-Barāʾ ʿĀmir ibn Mālik was a respected chieftain of the Najd region who visited Madinah and was deeply impressed by Islam, though he never accepted it outright. He proposed that the Prophet (ﷺ) send a group of Companions to preach in Najd, guaranteeing their safety under his own protection as a senior chieftain, an offer he made sincerely and in good faith. The Prophet (ﷺ) sent seventy Companions, mostly drawn from Ahl aṣ-Ṣuffah, on this basis. Abū al-Barāʾ's protection was honored by most of the tribes of Najd, but a rival and hostile chieftain, ʿĀmir ibn al-Ṭufayl, reportedly a relative of his, disregarded it entirely and orchestrated the massacre of the entire delegation at Biʼr Maʿūnah.
