Say thou: I simply call upon Allah, and I associate not with Him any-one. 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: Lo! none can protect me from Allah, nor can I find any refuge beside Him 22 "(Mine is) but conveyance (of the truth) from Allah and His Messages (of Islamic Monotheism), and whosoever disobeys Allah and His Messenger, then verily, for him is the Fire of Hell, he shall dwell therein 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 [doom] of which you were forewarned is near, or whether my Sustainer has set for it a distant term." 25 Knower He of the Unseen, and He discloses not His Unseen to anyone, 26 Except whom He has approved of messengers, and indeed, He sends before each messenger and behind him observers 27 (Messenger) so that He would know that the Messengers have conveyed the message of their Lord. He encompasses all that is with them and He keeps a precise account of all things". 28
