وَكَذَّبَ بِهِۦ قَوۡمُكَ وَهُوَ ٱلۡحَقُّۚ قُل لَّسۡتُ عَلَيۡكُم بِوَكِيلٖ
But your people (O Muhammad SAW) have denied it (the Quran) though it is the truth. Say: "I am not responsible for your affairs."
لِّكُلِّ نَبَإٖ مُّسۡتَقَرّٞۚ وَسَوۡفَ تَعۡلَمُونَ
For every news there is a fact, i.e. for everything there is an appointed term (and it is also said that for every deed there is a recompense) and you will come to know.
وَإِذَا رَأَيۡتَ ٱلَّذِينَ يَخُوضُونَ فِيٓ ءَايَٰتِنَا فَأَعۡرِضۡ عَنۡهُمۡ حَتَّىٰ يَخُوضُواْ فِي حَدِيثٍ غَيۡرِهِۦۚ وَإِمَّا يُنسِيَنَّكَ ٱلشَّيۡطَٰنُ فَلَا تَقۡعُدۡ بَعۡدَ ٱلذِّكۡرَىٰ مَعَ ٱلۡقَوۡمِ ٱلظَّـٰلِمِينَ
And when you (Muhammad SAW) see those who engage in a false conversation about Our Verses (of the Quran) by mocking at them, stay away from them till they turn to another topic. And if Shaitan (Satan) causes you to forget, then after the remembrance sit not you in the company of those people who are the Zalimun (polytheists and wrong-doers, etc.).
وَمَا عَلَى ٱلَّذِينَ يَتَّقُونَ مِنۡ حِسَابِهِم مِّن شَيۡءٖ وَلَٰكِن ذِكۡرَىٰ لَعَلَّهُمۡ يَتَّقُونَ
Those who fear Allah, keep their duty to Him and avoid evil are not responsible for them (the disbelievers) in any case, but (their duty) is to remind them, that they may avoid that (mockery at the Quran). [The order of this Verse was cancelled (abrogated) by the Verse 4:140].
