"Alif, Lam, Meem. This is the Book about which there is no doubt, a guidance for those conscious of Allah - Who believe in the unseen, establish prayer, and spend out of what We have provided for them, And who believe in what has been revealed to you, [O Muhammad], and what was revealed before you, and of the Hereafter they are certain [in faith]. Those are upon [right] guidance from their Lord, and it is those who are the successful." [Qur'an, 2:1-5]
