The Idolators ask for a Miracle

Allah states that out of their disbelief and stubbornness, the idolaters asked why is not a miracle sent down to the Messenger from his Lord, just like the earlier Messengers For instance, the disbelievers were being stubborn when they asked the Prophet to turn As-Safa into gold, to remove the mountains from around them, and to replace them with green fields and rivers. Allah said,

﴿ وَمَا مَنَعَنَآ أَن نُّرۡسِلَ بِٱلۡأَيَـٰتِ إِلَّآ أَن ڪَذَّبَ بِہَا ٱلۡأَوَّلُونَ‌ۚ ﴾

(And nothing stops Us from sending the Ayat but that the people of old denied them.)(17:59) Allah said here,

﴿ إِنَّمَآ أَنتَ مُنذِرُ ﴾

(You are only a warner), and your duty is only to convey Allah's Message which He has ordered you,

﴿ لَّيۡسَ عَلَيۡكَ هُدَٮٰهُمۡ وَلَـٰڪِنَّ ٱللَّهَ يَهۡدِى مَن يَشَآءُ‌ۗ ﴾

(Not upon you is their guidance, but Allah guides whom He wills.)(2:272) Allah said;

﴿ وَلِكُلِّ قَوۡمٍ هَادٍ ﴾

(And to every people there is a guide.) meaning that for every people there has been a caller, according to Ibn `Abbas and as narrated from him by Ali bin Abi Talhah. Allah said in a similar Ayah, a

﴿ وَإِن مِّنۡ أُمَّةٍ إِلَّا خَلَا فِيہَا نَذِيرٌ۬ ﴾

(And there never was a nation but a warner had passed among them.)(35:24) Similar has reported from Qatadah and `Abdur-Rahman bin Zayd.

﴿ ٱللَّهُ يَعۡلَمُ مَا تَحۡمِلُ ڪُلُّ أُنثَىٰ وَمَا تَغِيضُ ٱلۡأَرۡحَامُ وَمَا تَزۡدَادُ‌ۖ وَڪُلُّ شَىۡءٍ عِندَهُ ۥ بِمِقۡدَارٍ • عَـٰلِمُ ٱلۡغَيۡبِ وَٱلشَّہَـٰدَةِ ٱلۡڪَبِيرُ ٱلۡمُتَعَالِ ﴾

(8. Allah knows what every female bears, and by how much the wombs fall short (of their time or number) or exceed. Everything with Him is in (due) proportion.) (9. All-Knower of the unseen and the seen, the Most Great, the Most High.)
