(Ankabooth ) 29 : 26
فَآمَنَ لَهُ لُوطٌ ۘ وَقَالَ إِنِّي مُهَاجِرٌ إِلَىٰ رَبِّي ۖ إِنَّهُ هُوَ الْعَزِيزُ الْحَكِيمُ
Then Looth believed him; He said: "Indeed, I will emigrate to my Lord, Indeed He is the Exalted in Might, the Wise".
When the son of Ibrahim’s brother i.e. Looth saw the supernatural escape of Ibrahim from the Fire, he believed. Then after that event, Ibrahim said as mentioned in this verse and he along with Looth and Sarah migrated to Palestine.
