فَانطَلَقَا حَتَّى إِذَا أَتَيَا أَهْلَ قَرْيَةٍ اسْتَطْعَمَا أَهْلَهَا فَأَبَوْا أَن يُضَيِّفُوهُمَا فَوَجَدَا فِيهَا جِدَارًا يُرِيدُ أَن يَنقَضَّ فَأَقَامَهُ قَالَ لَوْ شِئْتَ لَاتَّخَذْتَ عَلَيْهِ أَجْرًا
So they went on until they came to the people of a town. They asked its people for food, but they refused to extend them any hospitality. There they found a wall which was about to collapse, so he erected it. He said, ‘Had you wished, you could have taken a wage for it.’
