Say: 'I call only upon my Lord, and I do not associate with Him anyone. 20 Say, "I do not possess any power to harm or benefit you". 21 Say: “None can protect me from Allah, nor can I find a refuge apart from Him. 22 except a deliverance from Allah and His Messages. He who disobeys Allah and His Messenger, for him is the Fire of Gehenna, which he will be in for ever. 23 (They shall not change their ways) until they see that against which they had been warned, and then they will know whose helpers are weaker and whose supporters are fewer in number. 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 does not disclose His Unseen to anyone, 26 except the messenger whom He has chosen. He sends down guardians who walk before them and behind them, 27 So that He may know that they have truly delivered the messages of their Lord, and He encompasses what is with them and He records the number of all things. 28
