Say, "I call only upon my Lord and do not associate anyone else with Him." 20 Say, "I do not possess any power to harm or benefit you". 21 Say: Surely no one can protect me against Allah, nor can I find besides Him any place of refuge: 22 if I should fail to convey [to the world whatever illumination comes to me] from God and His messages." Now as for him who rebels against God and His Apostle - verily, the fire of hell awaits him, therein to abide beyond the count of time. 23 Till, when they see that which they are promised, then they will know who it is that is weaker concerning helpers and less important concerning numbers. 24 Say: 'I do not know whether that which you are promised is nigh, or whether my Lord will appoint for it a space; 25 He is the Knower of the Unseen, and He does not disclose His Unseen to anyone 26 Other than an apostle He has chosen, when He makes a sentinel walk in front of him and a sentinel behind, 27 In order to see that they have conveyed the messages of their Lord – and His knowledge encompasses all whatever they have, and He has kept all things accounted for. 28
