Say: I only call upon my Lord, and I do not associate any one with Him. 20 Say: 'Surely I possess no power over you, either for hurt or for rectitude.' 21 Say, "Indeed, there will never protect me from Allah anyone [if I should disobey], nor will I find in other than Him a 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 Till (the day) when they shall behold that which they are promised (they may doubt); but then they will know (for certain) who is weaker in allies and less in multitude. 24 Say: "I do not know whether that [doom] of which you were forewarned is near, or whether my Sustainer has set for it a distant term." 25 (He is) the Knower of the Unseen, and He revealeth unto none His secret, 26 except the messenger whom He has chosen. He sends down guardians who walk before them and behind them, 27 That he may know that they have conveyed the messages of their Lord; and He has encompassed whatever is with them and has enumerated all things in number. 28
