35وَإِن كانَ كَبُرَ عَلَيكَ إِعراضُهُم فَإِنِ استَطَعتَ أَن تَبتَغِيَ نَفَقًا فِي الأَرضِ أَو سُلَّمًا فِي السَّماءِ فَتَأتِيَهُم بِآيَةٍ ۚ وَلَو شاءَ اللَّهُ لَجَمَعَهُم عَلَى الهُدىٰ ۚ فَلا تَكونَنَّ مِنَ الجاهِلينَN. J. DawoodIf you find their aversion hard to bear, seek if you can a chasm in the earth or a ladder to the sky by which you may bring them a sign. Had God pleased He would have given them guidance, one and all. Do not be foolish, then.
