'Abdullah bin 'Amr bin Al-As

Abdullah ibn Amr ibn al-As al-Qurashi al-Sahmi, may Allah be pleased with him, was one of the most prolific and scholarly of the companions of the Prophet ﷺ, having been given express permission by the Prophet ﷺ to write down his hadiths — an authorization not given to most companions who were initially discouraged from writing to avoid confusion with the Quran. He compiled a collection known as al-Sahifa al-Sadiqa (the Truthful Scroll), one of the earliest written hadith compilations, which was still being transmitted generations after his death. He was the son of the celebrated general and conqueror Amr ibn al-As and embraced Islam before his father, which caused some tension in the family. He was known for his extraordinary asceticism and worship — the Prophet ﷺ famously counseled him to moderate his fasting and night prayer, reminding him that his body and his family had rights over him. He narrated thousands of hadiths on nearly every topic of Islamic practice and ethics, covering prayer, fasting, family life, governance, trade, and eschatology. His narrations appear in all six major hadith collections. He passed away around 65–68 AH.
