Hijrah (migration for the sake of Allah)

إِنَّ ٱلَّذِينَ ءَامَنُوا۟ وَٱلَّذِينَ هَاجَرُوا۟ وَجَـٰهَدُوا۟ فِى سَبِيلِ ٱللَّهِ أُو۟لَـٰٓئِكَ يَرْجُونَ رَحْمَتَ ٱللَّهِ ۚ وَٱللَّهُ غَفُورٌ رَّحِيمٌ

Indeed, those who have believed and those who have emigrated and fought in the cause of Allāh - those expect the mercy of Allāh. And Allāh is Forgiving and Merciful.
