5-50 Muhammad ibn al-Hassan ibn Ahmad ibn al-Walid - may God be pleased with him - narrated that Muhammad ibn al-Hassan al-Saffar quoted Ibrahim ibn Hashim, on the authority of Abdul Rahman ibn Himad, on the authority of Ibrahim ibn Abdul-Hamid, on the authority of Abi Usamah,

“Aba Abdullah as-Sadiq (MGB) asked me, ‘Do you want me to inform you about five things which no one is aware of?’ I said, ‘Yes.’ He (MGB) replied, ‘Verily the knowledge of the Hour is with God (alone). It is He Who sends down rain, and He Who knows what is in the wombs. Nor does anyone know what it is that he will earn on the morrow: Nor does anyone know in what land he is to die. Verily with God is full knowledge and He is acquainted (with all things).’”
