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 And there are those of them who hear you, but can you make the deaf to hear though they will not understand? 42 And among them is one who gazes at you; so will you guide the blind* even if they cannot perceive? (* Deaf or blind to guidance.) 43 Verily Allah will not deal unjustly with man in aught: It is man that wrongs his own soul. 44 And on the Day when He shall gather them [unto Himself, it will seem to them] as if they had not tarried [on earth] longer than an hour of a day, knowing one another; [and] lost indeed will be they who [in their lifetime] considered it a lie that they were destined to meet God, and [thus] failed to find the right way. 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 its Messenger. Then, when their Messenger comes the matter is justly decided between them; they are not wronged. 47 They say, "When will this promise come to pass -- if you speak the truth?" 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, "If His punishment comes upon you in the dead of night, or by the light of day, how will the guilty escape it? 50 Will you, then, believe in it [only] after it has come to pass - [on the Day when you will be asked, 'Do you believe in it] now, after having [contemptuously] called for its speedy advent?' 51 Then it will be said to those who had wronged, "Taste the punishment of eternity; are you being recompensed except for what you used to earn?" 52 They ask you, "Is that (punishment) true?" Tell them, "It certainly is. I swear by my Lord. You can not escape from (God's retribution)". 53
