‘A’isha said that she heard God’s messenger say, “He who discusses any aspect of God’s decree will be questioned about it on the day of resurrection, but he who does not discuss it will not be questioned about it.”
I went to Ubayy b. Ka‘b and said to him, “I am confused about the divine decree, so tell me something by means of which God may remove the confusion from my mind.” He replied, “Were God to punish everyone in the heavens and the earth He would do so without being unjust to them, and were He to show mercy to them His mercy would be much better than their actions merited. Were you to spend in support of God’s cause an amount of gold equivalent to Uhud, God would not accept it from you till you believed in the divine decree and knew that what has come to you could not miss you and that what has missed you could not come to you. Were you to die believing anything else you would enter hell.” He said: I then went to ‘Abdallah b. Mas'ud and he said something to the same effect. I next went to Hudhaifa b. al-Yaman and he said something to the same effect. I next went to Zaid b. Thabit and he told me something from the Prophet to the same effect.
