It has been narrated by Salama b. al-Akwa' that he visited al-Hajjaj who said to him:
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 صلى الله عليه وسلم أَذِنَ لِي فِي الْبَدْوِ .
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.
