The prohibition against a Muhajir returning to settle in his former homeland

It has been narrated by Salama b. al-Akwa' that he visited al-Hajjaj who said to him: O son of al-Akwa', you have turned apostate and have come to live again in the desert with the Bedouins (after your migration). He said: No, but the Messenger of Allah ﷺ has permitted me to live in the desert.

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا حَاتِمٌ، - يَعْنِي ابْنَ إِسْمَاعِيلَ - عَنْ يَزِيدَ بْنِ أَبِي، عُبَيْدٍ عَنْ سَلَمَةَ بْنِ الأَكْوَعِ، أَنَّهُ دَخَلَ عَلَى الْحَجَّاجِ فَقَالَ يَا ابْنَ الأَكْوَعِ ارْتَدَدْتَ عَلَى عَقِبَيْكَ تَعَرَّبْتَ قَالَ لاَ وَلَكِنْ رَسُولُ اللَّهِ ﷺ أَذِنَ لِي فِي الْبَدْوِ .
