Whoever disobeys God and His Messenger will go to hell, wherein he will live 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 know not whether the (Punishment) which ye are promised is near, or whether my Lord will appoint for it a distant term. 25 "He (alone) knows the Unseen, nor does He make any one acquainted with His Mysteries,- 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
