“O ye who believe! Shall I lead you to a bargain that will save you from a grievous Penalty?-
That ye believe in God and His Messenger, and that ye strive (your utmost) in the Cause of God, with your property and your persons: That will be best for you, if ye but knew!
He will forgive you your sins, and admit you to Gardens beneath which Rivers flow, and to beautiful mansions in Gardens of Eternity: that is indeed the Supreme Achievement.
And another (favour will He bestow,) which ye do love,- help from God and a speedy victory. So give the Glad Tidings to the Believers.” (Surah Al Saff 61:10-13)
