It has been stated earlier that Abdullah ibn ‘Amr was specifically instructed by Holy Prophet (SAWS) to write Ahadith. He therefore compiled a big script and named it “Al Sahfah al Sadiqah” (The script of Truth). Abdullah ibn ‘Amr was very precautious in preserving this script. Mujahid, one of his favorite pupils says, “I went to Abdullah ibn Amr and took in hand a script placed beneath his cushion. He stopped me. I said, “you never save anything from me.” He replied,
“This is the “Sadiqah” (the Script of Truth). It is what I heard from the Holy Prophet (SAWS). No other narrator intervenes between him and me. If this script, the Book of Allah and Wahaz (his agricultural land) are secured for me, I would never care about the rest of the world (Bayan ul Ilm).
This Script remained with his children. His grandson, Amr ibn Shuaib used to teach the Ahadith contained in it. Yahya ibn Ma’in and Au ibn al Madini have said that every tradition reported by Amr ibn Shuaib in any book of hadith has been taken from this script (Tahzeeb ul Tahzeeb). Ibn al Asir says that this script contained one thousand Ahadith.
