Say (O Muhammad SAW): "O mankind! I am (sent) to you only as a plain warner." 49 Then (as for) those who believe and do good, they shall have forgiveness and an honorable sustenance. 50 But those who strive against Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), to frustrate and obstruct them, they will be dwellers of the Hell-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 He may make that which the devil proposeth a temptation for those in whose hearts is a disease, and those whose hearts are hardened - Lo! the evil-doers are in open schism - 53 And that those who have been given the knowledge may know that it is the truth from your Lord, so they may believe in it and their hearts may be lowly before it; and most surely Allah is the Guide of those who believe into a right path. 54 The unbelievers will never cease to doubt it until the Hour overtakes them suddenly or the punishment of the Barren Day comes upon them. 55 On that Day all sovereignty shall be Allah's and He will judge among them. Then those who believed and acted righteously shall be in Gardens of Bliss. 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
