On several occasions in his writings Ibn Sīnā discusses the problem of destiny (al-qadar), by which he means primarily the problem of reconciling the divine determination of human acts and characters with the rewards and punishments of the after-life, in such a way as to safeguard God's justice to man. This aspect of the problem of theodicy had arisen long before his time out of statements of the Qur'ān and Traditions, and had been settled in their own fashions by Mu'tazilite and predestinarian theologians. Ibn Slna as a philosopher could hardly avoid offering a solution, if only to satisfy the doubts of his Muslim public; but he goes beyond a perfunctory answer, and seems to show a genuine interest in finding an intellectually convincing solution consistent with his own philosophy.
