Say, [O Muhammad], "I only invoke my Lord and do not associate with Him anyone." 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 thou: verily none can protect me from Allah, nor can I find beside Him any refuge. 22 But [I have for you] only notification from Allah, and His messages." And whoever disobeys Allah and His Messenger - then indeed, for him is the fire of Hell; they will abide 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 (Muhammad), say, "I do not know whether that with which you have been threatened is close by or whether my Lord will prolong the time of its coming. 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 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
