It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Four things concerning the son of Adam have already been decided (in destiny): his creation, his character, his provision and the term of his life."
No one narrated this hadith from al-Qasim bin Abd al-Rahman (may Allah have mercy on him) except Isa bin al-Musayyib (may Allah have mercy on him), and Safwan bin Hubayrah (may Allah have mercy on him) is alone in narrating it.
