Abdullah ibn Amr ibn al-As

Abdullah ibn Amr ibn al-As was the son of the great general Amr ibn al-As, but unlike his father he was primarily a scholar rather than a warrior. He was younger than his father by only a few years — some sources say he and his father converted in the same period, with the son slightly earlier. He was among the few companions whom the Prophet explicitly permitted to write down hadiths. He compiled what became known as the Sahifa al-Sadiqa (the Truthful Scroll), which may be the oldest written collection of hadiths, comprising over 1,000 narrations. He narrated over 700 hadiths that appear in the major collections. He was known for his extreme asceticism — he fasted every day and prayed every night, so much that the Prophet reportedly told him: 'Your body has rights over you, your eyes have rights over you, and your family have rights over you' — and prescribed a moderate schedule of fasting and prayer. He lived in Egypt after the conquests and settled there. He died in 63 AH, possibly in Ta'if or Egypt. His collection of hadiths was later found in the possession of his grandson and is considered an important early source.
