فَلَعَلَّكَ تَارِكُۢ بَعۡضَ مَا يُوحَىٰٓ إِلَيۡكَ وَضَآئِقُۢ بِهِۦ صَدۡرُكَ أَن يَقُولُواْ لَوۡلَآ أُنزِلَ عَلَيۡهِ كَنزٌ أَوۡ جَآءَ مَعَهُۥ مَلَكٌۚ إِنَّمَآ أَنتَ نَذِيرٞۚ وَٱللَّهُ عَلَىٰ كُلِّ شَيۡءٖ وَكِيلٌ
So, possibly you would leave some ( ayat) (verses, signs) of what is revealed to you, and your breast would be straitened by it, for that they say, "if only a hoarding had been sent down upon him, or an Angel had come with him!" Surely you are only a warner; and Allah is an Ever-Trusted Trustee over everything.
أَمۡ يَقُولُونَ ٱفۡتَرَىٰهُۖ قُلۡ فَأۡتُواْ بِعَشۡرِ سُوَرٖ مِّثۡلِهِۦ مُفۡتَرَيَٰتٖ وَٱدۡعُواْ مَنِ ٱسۡتَطَعۡتُم مِّن دُونِ ٱللَّهِ إِن كُنتُمۡ صَٰدِقِينَ
Or (even) do they say, "He has fabricated it!" Say, "Then come up with ten Surahs the like of it, fabricated; and invoke whomever you are able, apart from Allah, in case you are sincere."
فَإِلَّمۡ يَسۡتَجِيبُواْ لَكُمۡ فَٱعۡلَمُوٓاْ أَنَّمَآ أُنزِلَ بِعِلۡمِ ٱللَّهِ وَأَن لَّآ إِلَٰهَ إِلَّا هُوَۖ فَهَلۡ أَنتُم مُّسۡلِمُونَ
So, in case they (i.e. the disbelievers) do not respond to you, then know that it has been sent down only with the knowledge of Allah and that there is no god except He. So are you (now) Muslims? (i.e., have you surrendered "to Him"?)
مَن كَانَ يُرِيدُ ٱلۡحَيَوٰةَ ٱلدُّنۡيَا وَزِينَتَهَا نُوَفِّ إِلَيۡهِمۡ أَعۡمَٰلَهُمۡ فِيهَا وَهُمۡ فِيهَا لَا يُبۡخَسُونَ
Whoever is willing (to gain) the present life (Literally: the lowly life, i.e., the life of this world) and its adornment, We will pay them therein in full for their deeds and they shall not be depreciated (i.e., their deeds will not be depreciated) therein.
