Khameer bin Malik says: When, during the era of Sayyiduna Uthman (may Allah be pleased with him), the order was given to change the manuscripts of the Qur'an, Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: Whoever among you can betray his manuscript, let him do so, because whoever betrays anything will bring it with him on the Day of Resurrection. Then he said: I have heard seventy (70) surahs from the blessed mouth of the Noble Prophet (peace and blessings be upon him), should I abandon them? In another narration it is stated: I had heard seventy (70) surahs from the blessed mouth of the Noble Prophet (peace and blessings be upon him) at a time when Zaid bin Thabit (may Allah be pleased with him) was still a child in matters of writing.
