It is narrated from Hazrat Sulaiman bin Surad (may Allah be pleased with him) on the authority of Ubayy bin Ka'b (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Gabriel (peace be upon him) and Michael (peace be upon him) came to me. Gabriel (peace be upon him) said: Recite the Noble Qur'an on one letter. Michael (peace be upon him) said: Request an addition from them, until it reached seven letters.
