Mutal Loss and Gain
1. Whatsoever is in the heavens and whatsoever is on the earth glorifies Allah. His is the dominion, and to Him belong all the praises and thanks, and He is Able to do all things.
6. That was because there came to them their Messengers with clear proofs (signs), but they said: “Shall mere men guide us?” So they disbelieved and turned away (from the truth), and Allah was not in need (of them). And Allah is Rich (Free of all wants), Worthy of all praise.
7. The disbelievers pretend that they will never be resurrected (for the Account). Say (O Muhammad ): “Yes! By my Lord, you will certainly be resurrected, then you will be informed of (and recompensed for) what you did, and that is easy for Allah.
9. (And remember) the Day when He will gather you (all) on the Day of Gathering, that will be the Day of mutual loss and gain (i.e. loss for the disbelievers as they will enter the Hell-fire and gain for the believers as they will enter Paradise). And whosoever believes in Allah and performs righteous good deeds, He will remit from him his sins, and will admit him to Gardens under which rivers flow (Paradise) to dwell therein forever, that will be the great success.
10. But those who disbelieved (in the Oneness of Allah – Islamic Monotheism) and denied Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), they will be the dwellers of the Fire, to dwell therein forever. And worst indeed is that destination.
11. No calamity befalls, but with the Leave [i.e. decision and Qadar (Divine Preordainments)] of Allah, and whosoever believes in Allah, He guides his heart [to the true Faith with certainty, i.e. what has befallen him was already written for him by Allah from the Qadar (Divine Preordainments)], and Allah is the All-Knower of everything.
14. O you who believe! Verily, among your wives and your children there are enemies for you (i.e. may stop you from the obedience of Allah), therefore beware of them! But if you pardon (them) and overlook, and forgive (their faults), then verily, Allah is Oft-Forgiving, Most Merciful.
16. So keep your duty to Allah and fear Him as much as you can; listen and obey; and spend in charity, that is better for yourselves. And whosoever is saved from his own covetousness, then they are the successful ones.
18. All-Knower of the unseen and seen, the All-Mighty, the All-Wise.
