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 صلى الله عليه وسلم أَذِنَ لِي فِي الْبَدْوِ .
