Everything in this book that is narrated from Masma ibn Malik Al-Basri has been transmitted by me from my father - may Allah سبحانه وتعالى be pleased with him - from Sad ibn Abdullah, from Ahmad ibn Muhammad ibn Isa, from Al-Husayn ibn Said, from Al-Qasim ibn Muhammad, from Aban, from Masma ibn Malik Al-Basri. He is also known as Masma ibn Abd Al-Malik Al-Basri, and his nickname was Kardin. He was an Arab from Banu Qays ibn Thalabah and was known by the kunya Abu Sayyar. It is reported that when Imam Jafar ibn Muhammad Al-Sadiq عليه السلام first saw him, he asked: "What is your name?" He replied: "Masma." The Imam asked: "Son of whom?" He replied: "Son of Malik." The Imam said: "Rather, you are Masma ibn Abd Al-Malik."
