2. Abu Ali al-Ash‘ariy has narrated from ‘Isa ibn Ayyub from Afi ibn Mahziyar from those whom he has mentioned who has narrated the following: “Abu ‘Abd Allah , has said that when Adam , was shown his offspring, he looked at Dawud, he liked him and donated fifty years of his life to him. He (the Imam) said that Jibril and Michael came to him and the angel of death wrote a document about fifty years of his life being donated. When the time of his death came the angel of death came and Adam , said that fifty years of his life still has remained, and he said, ‘What about fifty years that you donated to your son Dawud ? 5 He (the Imam) said, ‘It was because that he had forgotten or denied it. Jibril and Michael came and testified about the matter, then the angel of death took away his soul . 5 Abu ‘Abd Allah , has said, ‘It was the first check (certificate or deed) that was ever written on earth. 5 ”
