Say (O Muhammad SAW): "O mankind! I am (sent) to you only as a plain warner." 49 "Those who believe and work righteousness, for them is forgiveness and a sustenance most generous. 50 While those who strive to thwart Our revelations, such are rightful owners of the Fire. 51 Yet whenever We sent forth any apostle or prophet before thee, and he was hoping [that his warnings would be heeded,] Satan would cast an aspersion on his innermost aims: but God renders null and void whatever aspersion Satan may cast; and God makes His messages clear in and by themselves for God is all-knowing, wise. 52 He would make Satan's temptations a trial for those whose hearts are hard and sick. The wrong-doers are far away from the Lord, 53 so that those who are given knowledge may realize that this is the truth from your Lord and thus believe in it, and so that in their hearts they may humbly submit to Him. God will surely guide the faithful to a straight path. 54 Those who deny the truth will continue in doubt until the [Last] Hour suddenly comes upon them or the scourge of the woeful Day descends upon them. 55 The kingdom on that day shall be Allah's; He will judge between them; so those who believe and do good will be in gardens of bliss. 56 but for those who disbelieved Our verses and belied there awaits a humbling punishment. 57
