Abd Allah ibn Amr ibn al-As
'Abd Allah ibn 'Amr ibn al-'As was a companion of the Islamic prophet Muhammad. He was the author of "Al-Sahifah al-Sadiqah", 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. The prophet 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 prophet 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 Prophet Muhammad.
