Abd Allah ibn Amr ibn al-As

He was the author of "Al-Sahifah al-Sadiqah" ("The Truthful Script", Arabic: الصحيفة الصادقة), the first known hadith compilation document.

Muhammad was said to have shown a preference for Abd Allah ibn 'Amr due to his knowledge.

[4] He participated in the Battle of Siffin as he was obliged to follow his father in the ranks of Mu'awiya.

[4] Abd Allah succeeded his father Amr as governor of Egypt for a few weeks in early 664 before Mu'awiya, who had become caliph in 661, appointed his own brother Utba ibn Abi Sufyan to the post.

[6][7] His work Al-Sahifah al-Sadiqah remained in his family and was used by his grandson 'Amr ibn Shu'ayb.
