﴿ ۞ فَلَمَّا قَضَىٰ مُوسَى ٱلْأَجَلَ وَسَارَ بِأَهْلِهِۦٓ ءَانَسَ مِن جَانِبِ ٱلطُّورِ نَارًۭا قَالَ لِأَهْلِهِ ٱمْكُثُوٓا۟ إِنِّىٓ ءَانَسْتُ نَارًۭا لَّعَلِّىٓ ءَاتِيكُم مِّنْهَا بِخَبَرٍ أَوْ جَذْوَةٍۢ مِّنَ ٱلنَّارِ لَعَلَّكُمْ تَصْطَلُونَ ﴾

“And when Moses had fulfilled his term and was wandering with his family [in the desert], he per­ceived a fire on the slope of Mount Sinai; [and so] he said to his family: “Wait here. Behold, I perceive a fire [far away]; perhaps I may bring you from there some tiding, or [at least] a burning brand from the fire, so that you might warm yourselves.”
