And if they call you a liar, say: My work is for me and your work for you; you are clear of what I do and I am clear of what you do. 41 Among them are some who (pretend to) listen to thee: But canst thou make the deaf to hear,- even though they are without understanding? 42 And of them are some who look at thee, so canst thou guide the blind, even though they see not? 43 Surely Allah does not wrong men; they rather wrong themselves. 44 And on the Day when He will gather them, [it will be] as if they had not remained [in the world] but an hour of the day, [and] they will know each other. Those will have lost who denied the meeting with Allah and were not guided 45 Whether We let you see (during your lifetime) some of the chastisement with which We threaten them, or We call you unto Us (before the chastisement strikes them), in any case they are bound to return to Us. Allah is witness to all what they do. 46 Every nation has a messenger. Once their messenger has come, judgement will be passed upon them in all fairness and they will not be wronged. 47 They say: "When is this promise going to come, if what you say is true?" 48 Say (O Muhammad SAW): "I have no power over any harm or profit to myself except what Allah may will. For every Ummah (a community or a nation), there is a term appointed; when their term is reached, neither can they delay it nor can they advance it an hour (or a moment)." (Tafsir Al-Qurtubi). 49 Say: Have ye thought: When His doom cometh unto you as a raid by night, or in the (busy) day; what is there of it that the guilty ones desire to hasten? 50 Is it then, that when it has actually befallen, that you will believe in it? What! Now (you believe)? And you used (aforetime) to hasten it on!" 51 Then it shall be said to those who were unjust: Taste abiding chastisement; you are not requited except for what you earned. 52 They enquire of you if this will really happen. Tell them, "Yes, by my Lord. Most certainly it will happen, and you cannot avert it." 53
