Say: O mankind! I am only a plain warner unto you. 49 Those who believe and do good deeds shall be forgiven and shall receive an honourable provision. 50 whereas those who strive against Our messages, seeking to defeat their purpose - they are destined for the blazing fire. 51 Never sent We a messenger or a prophet before thee but when He recited (the message) Satan proposed (opposition) in respect of that which he recited thereof. But Allah abolisheth that which Satan proposeth. Then Allah establisheth His revelations. Allah is Knower, Wise; 52 That he may make that which the Satan casteth forth a temptation for those in whose heart is a disease and whose hearts are hardened - and the wrong-doers are in divergence far-off 53 And so that the people given the knowledge may know that it is the truth from your Lord, in order that they may accept faith in it, therefore their hearts may humble before Him; and indeed Allah will guide the believers on the Straight Path. 54 The infidels will remain in doubt about it till the Hour overtakes them unawares, or the punishment of the barren day destructive should come upon them. 55 For Allah only is the kingship on that day; He will judge between them; so those who believed and did good deeds are in Gardens of content. 56 whereas for those who were bent on denying the truth and gave the lie to Our messages, there shall be shameful suffering in store. 57
