"Allah has revealed [from time to time] the most beautiful Message in the form of a Book, consistent with itself, [yet] repeating [its teaching in various aspects]: the skins of those who fear their Lord tremble thereat; then their skins and their hearts do soften to the celebration of Allah's praises. Such is the guidance of Allah: He guides therewith whom He pleases, but such as Allah leaves to stray, can have none to guide."— Yusuf Ali translation
