The Idolators ask for a Miracle Allah says:وَيَقُولُ الَّذِينَ كَفَرُواْ لَوْلا أُنزِلَ عَلَيْهِ ايَةٌ مِّن رَّبِّهِAnd the disbelievers say:"Why is not a sign sent down to him from his Lord!"Allah states that out of their disbelief and stubbornness, the idolators 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 مَنَعَنَأ أَن نُّرْسِلَ بِالاٌّيَـتِ إِلاَّ أَن كَذَّبَ بِهَا الاٌّوَّلُونَAnd nothing stops Us from sending the Ayat but that the people of old denied them. (17:59)Allah said here,إِنَّمَا أَنتَ مُنذِرٌYou are only a warner,and your duty is only to convey Allah's Message which He has ordered you,لَّيْسَ عَلَيْكَ هُدَاهُمْ وَلَـكِنَّ اللَّهَ يَهْدِى مَن يَشَأءُNot upon you is their guidance, but Allah guides whom He wills. (2:272)Allah said;وَلِكُلِّ قَوْمٍ هَادٍAnd 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,وَإِن مِّنْ أُمَّةٍ إِلاَّ خَلَ فِيهَا نَذِيرٌAnd there never was a nation but a warner had passed among them. (35:24) Similar has reported from Qatadah and Abdur-Rahman bin Zayd
