Believers, shall I direct you to a commerce that will deliver you from a grievous chastisement? 10 [It is that] you believe in Allah and His Messenger and strive in the cause of Allah with your wealth and your lives. That is best for you, if you should know. 11 He will forgive you your sins, and make you enter Gardens whereunder rivers flow, and happy abodes in Gardens Everlasting. That is the mighty achievement. 12 He will give you another blessing which you desire: help from God and imminent victory. Give good tidings [O Muhammad] to believers! 13 O ye who believe! be Allah's helpers, even as 'Isa, son of Maryam, said unto the disciples: who shall be my helpers unto Allah? The disciples said: we are Allah's helpers. Then a part of the Children of Israil believed, and part disbelieved. Then We strengthened those who believed against their foe; wherefore they became triumphant. 14
