إِذْ قَالَ مُوسَىٰ لِأَهْلِهِۦٓ إِنِّىٓ ءَانَسْتُ نَارًۭا سَـَٔاتِيكُم مِّنْهَا بِخَبَرٍ أَوْ ءَاتِيكُم بِشِهَابٍۢ قَبَسٍۢ لَّعَلَّكُمْ تَصْطَلُونَ
(Remember) when Moses said unto his household: Lo! I spy afar off a fire; I will bring you tidings thence, or bring to you a borrowed flame that ye may warm yourselves.
