6 : 109
وَأَقۡسَمُواْ بِٱللَّهِ جَهۡدَ أَيۡمَٰنِهِمۡ لَئِن جَآءَتۡهُمۡ ءَايَةٞ لَّيُؤۡمِنُنَّ بِهَاۚ قُلۡ إِنَّمَا ٱلۡأٓيَٰتُ عِندَ ٱللَّهِۖ وَمَا يُشۡعِرُكُمۡ أَنَّهَآ إِذَا جَآءَتۡ لَا يُؤۡمِنُونَ
And they swear by Allāh their strongest oaths that if a sign came to them, they would surely believe in it. Say, "The signs are only with [i.e., from] Allāh." And what will make you perceive that even if it [i.e., a sign] came, they would not believe.
