وَاعْلَمْ أَنَّ الْبَصْرَةَ مَهْبِطُ إِبْلِيسَ، وَمَغْرِسُ الْفِتَنِ، فَحَادِثْ أَهْلَهَا بِالْإِحْسَانِ إِلَيْهِمْ، وَاحْلُلْ عُقْدَةَ الْخَوْفِ عَنْ قُلُوبِهِمْ.
You should know that Baṣrah is the place where Satan descends and mischiefs happen. Keep the people of this place pleased with good treatment and remove the knots of fear from their hearts.
