Qur'an, Saba', Surah 34:49-50
Say: "The Truth has arrived, and Falsehood neither creates anything new, nor restores anything."
Say: "If I am astray, I only stray to the loss of my own soul: but if I receive guidance, it is because of the inspiration of my Lord to me: it is He Who hears all things, and is (ever) near."
