Surah 68. Al-Qalam, Ayah 3

Instead of being out of his right mind, the Prophet of Allah had been raised to a great spiritual dignity, a reward that was not like an earthly reward that passes away, but one that was in the very core of his being, and would never fail him in any circumstances. He was really granted a nature and character far above the shafts of grief or suffering, slander or persecution.
