﴿ إِذْ رَءَا نَارًۭا فَقَالَ لِأَهْلِهِ ٱمْكُثُوٓا۟ إِنِّىٓ ءَانَسْتُ نَارًۭا لَّعَلِّىٓ ءَاتِيكُم مِّنْهَا بِقَبَسٍ أَوْ أَجِدُ عَلَى ٱلنَّارِ هُدًۭى ﴾

“Lo! he saw a fire [in the desert]; and so he said to his family: "Wait here! Behold, I perceive a fire [far away]: perhaps I can bring you a brand there from, or find at the fire some guidance."”

When he caught sight of a fire and said to his family namely to his wife ‘Wait here! — this was when he was leaving Midian heading for Egypt — Indeed I see a fire in the distance. Perhaps I can bring you a brand from it bring you a burning wick or a torch or find at the fire some guidance’ that is someone to guide me by showing me the proper route — for he had lost it in the darkness of the night. He Moses said ‘perhaps’ la‘alla because he could not be certain of fulfilling his promise.
