Say, "The Truth has come; now falsehood cannot succeed whatever it may do."

Sura #34 سورة سبأ Saba

49 Say (O Muhammad صلى الله عليه وسلم): "Al-Haqq (the truth i.e. the Qur'an and Allah's Revelation) has come, and Al-Batil [falsehood - Iblis (Satan)] can neither create anything nor resurrect (anything)."

50 Say: "If (even) I go astray, I shall stray only to my own loss. But if I remain guided, it is because of the Revelation of my Lord to me. Truly, He is All-Hearer, Ever Near (to all things)."

51 And if you could but see, when they will be terrified with no escape (for them), and they will be seized from a near place.

52 And they will say (in the Hereafter): "We do believe (now):" but how could they receive (Faith and the acceptance of their repentance by Allah) from a place so far off (i.e. to return to the worldly life again).

53 Indeed they did disbelieve (in the Oneness of Allah, Islam, the Qur'an and Muhammad صلى الله عليه وسلم) before (in this world), and they (used to) conjecture about the Unseen [i.e. the Hereafter, Hell, Paradise, Resurrection and the Promise of Allah (by saying) all that is untrue], from a far place.

54 And a barrier will be set between them and that which they desire [i.e. At-Taubah (turning to Allah in repentance) and the accepting of Faith], as was done in the past with the people of their kind. Verily, they have been in grave doubt.
