Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "Four things have been settled: creation, character, provision, and the appointed time of death. None of us earns (more) in place of another (that is, provision is fixed for each person)."
And he said: "Charity takes effect, whether it has been taken into possession or not."
