Surah 21. Al-Anbiya, Ayah 52

Reference is made to Abraham in many places. In xix. 42-49 it was with reference to his relations to his father: the problem was how a righteous man should deal with his father, when his duty to his father conflicts with his duty to Allah. Here the problem is: how a righteous man should deal with evil and overcome it; how he should fight against evil, and if he is subjected to the fire of persecution, how his firmness draws Allah's Mercy, and the very troubles he is placed in become his comfort and joy.
