Say (unto them, O Muhammad): I pray unto Allah only, and ascribe unto Him no partner. 20 Say: "Verily, it is not in my power to cause you harm or to endow you with consciousness of what is right." 21 Say: 'None shall protect me from Allah, and other than Him, I will find no refuge, 22 My duty is only to convey that which I receive from Him and His messages." For those who disobey God and His Messenger there is the fire of hell, wherein they will abide forever. 23 At length, when they see (with their own eyes) that which they are promised,- then will they know who it is that is weakest in (his) helper and least important in point of 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 The Knower of the unseen! so He does not reveal His secrets to any, 26 Except to a Messenger (from mankind) whom He has chosen (He informs him of unseen as much as He likes), and then He makes a band of watching guards (angels) to march before him and behind him. 27 so as to make manifest that it is indeed [but] their Sustainer's messages that these [apostles] deliver: for it is He who encompasses [with His knowledge] all that they have [to say,] just as He takes count, one by one, of everything [that exists]. 28
