The Qur'an as a Miracle

وَقَالُوا۟ لَوْلَآ أُنزِلَ عَلَيْهِ ءَايَـٰتٌ مِّن رَّبِّهِۦ ۖ قُلْ إِنَّمَا ٱلْـَٔايَـٰتُ عِندَ ٱللَّهِ وَإِنَّمَآ أَنَا۠ نَذِيرٌ مُّبِينٌ

But they say, "Why are not signs sent down to him from his Lord?" Say, "The signs are only with Allāh, and I am only a clear warner."
