Say (O Muhammad SAW): "O mankind! I am (sent) to you only as a plain warner." 49 The righteously striving believers will receive forgiveness and honorable sustenance. 50 whereas those who strive against Our Signs, seeking to profane them, they are the friends of the Fire! 51 Never did We send a Messenger or a Prophet before you (O Muhammad), but that whenever he had a desire, Satan interfered with that desire. Allah eradicates the interference of Satan and strengthens His Signs. Allah is All-Knowing, All-Wise. 52 [That is] so He may make what Satan throws in a trial for those within whose hearts is disease and those hard of heart. And indeed, the wrongdoers are in extreme dissension. 53 And [God renders Satan's aspersions null and void] so that they who are endowed with [innate] knowledge might know that this [divine writ] is the truth from thy Sustainer, and that they aught believe in it, and that their hearts might humbly submit unto Him. For, behold, God does guide onto a straight way those who have attained to faith 54 And those who disbelieve will not cease to be in doubt thereof until the Hour come upon them unawares, or there come unto them the doom of a disastrous day. 55 The order will be God's on that Day; He will judge between them. Then those who had come to believe and done the right will be in gardens of delight. 56 But those who did not believe and called Our revelations lies, will be given disgraceful punishment. 57
