(Qasas) 28 : 29
فَلَمَّا قَضَىٰ مُوسَى الْأَجَلَ وَسَارَ بِأَهْلِهِ آنَسَ مِنْ جَانِبِ الطُّورِ نَارًا قَالَ لِأَهْلِهِ امْكُثُوا إِنِّي آنَسْتُ نَارًا لَعَلِّي آتِيكُمْ مِنْهَا بِخَبَرٍ أَوْ جَذْوَةٍ مِنَ النَّارِ لَعَلَّكُمْ تَصْطَلُونَ
Then when Moses had completed the term and was traveling with his family, he perceived from the direction of the mount Sina a fire. He said to his family: "Stay here; indeed, I have perceived a fire. Perhaps I will bring you from there information or burning wood from the fire that you may warm yourselves".
