'Abd Allah ibn 'Amr ibn al-'As (Arabic: عبد الله بن عمرو بن العاص) (died 684 CE/65 AH, the son of 'Amr ibn al-'As of Banu Sahm) was a companion of the Islamic prophet Muhammad. He was the author of "Al-Sahifah al-Sadiqah" ("The Truthful Script", Arabic: الصحيفة الصادقة), The first known hadith compilation document which recorded about one thousand of Muhammad's narrations.
He embraced Islam in the year 7 AH a year before his father did, Amr ibn al-'As. Muhammad used to show preference to Abd Allah ibn 'Amr due to his knowledge. He was one of the first companions to write down the Hadith, after receiving permission from Muhammad to do so. Abu Huraira used to say that Abd Allah ibn 'Amr was more knowledgeable than him.
His work Al-Sahifah al-Sadiqah remained in his family and was used by his grandson 'Amr ibn Shu'ayb. Ahmad ibn Hanbal incorporated the whole of the work of Abd Allah ibn 'Amr in his voluminous book Musnad Ahmad ibn Hanbal thereby covering up for the missing Al-Sahifah al-Sadiqah which was written in the days of Muhammad.
