Say thou: I simply call upon Allah, and I associate not with Him any-one. 20 Say: 'Surely I possess no power over you, either for hurt or for rectitude.' 21 Say: "No one can save me from God, nor can I find a place of refuge apart from Him, 22 (My task is no more than) to deliver Allah's proclamation and His messages. And whoever disobeys Allah and His Messenger, surely the Fire of Hell awaits him; therein he will abide in perpetuity.” 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 what you are promised is imminent, or whether my Lord has set for it a far-off day. 25 [He is] Knower of the unseen, and He does not disclose His [knowledge of the] unseen to anyone 26 Except whom He has approved of messengers, and indeed, He sends before each messenger and behind him observers 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
