That his father said, "The Prophet ﷺ sent Muʿadh and Abu Musa to Yemen telling them. 'Treat the people with ease and don't be hard on them; give them glad tidings and don't fill them with aversion; and love each other, and don't differ." (Using translation from Bukhārī 3038)  

أحمد:١٩٦٩٩ – حَدَّثَنَا وَكِيعٌ حَدَّثَنَا شُعْبَةُ عَنْ سَعِيدِ بْنِ أَبِي بُرْدَةَ عَنْ أَبِيهِ

أَنَّ النَّبِيَّ ﷺ بَعَثَ مُعَاذًا وَأَبَا مُوسَى إِلَى الْيَمَنِ فَقَالَ بَشِّرُوا وَلَا تُنَفِّرُوا وَيَسِّرُوا وَلَا تُعَسِّرُوا وَتَطَاوَعَا وَلَا تَخْتَلِفَا قَالَ فَكَانَ لِكُلِّ وَاحِدٍ مِنْهُمَا فُسْطَاطًا يَكُونُ فِيهِ يَزُورُ أَحَدُهُمَا صَاحِبَهُ قَالَ أَبُو عَبْدِ الرَّحْمَنِ أَظُنُّهُ عَنْ أَبِي مُوسَى
