"Alif, Lam, Mim. This is the Book about which there is no doubt, a guidance for those who fear Allah - who believe in the unseen, establish the prayer and spend out of what We have provided for them. Who believe in what has been revealed to you 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 successful." [Al-Baqarah (2): 1-5]
