Say (O Muhammad SAW): "O mankind! I am (sent) to you only as a plain warner." 49 So those who believed and did good deeds, for them are forgiveness, and an excellent sustenance. 50 And those who strive in Our signs with the intention of disputing, are the people of fire. 51 And We have sent before thee no apostle or prophet but when he read the Satan cast forth suggestions in respect of his reading; then Allah abolisheth that which the Satan casteth forth; then Allah confirmeth His revelations; and Allah is 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 have received knowledge would know and believe that whatever happens with the Prophets and Messengers is the Truth from their Lord and will believe it. This will cause their hearts to become filled with awe. God guides the believers to the right 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 On that Day, all dominion shall [visibly] belong to God, He shall judge [all men and make a distinction] between them: thus, all who had attained to faith and did righteous deeds shall find themselves in gardens of bliss, 56 But those who did not believe and called Our revelations lies, will be given disgraceful punishment. 57
