Narrated Abu Burda:
That his father said, "The Prophet sent Mu'adh 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."
حَدَّثَنَا يَحْيَى، حَدَّثَنَا وَكِيعٌ، عَنْ شُعْبَةَ، عَنْ سَعِيدِ بْنِ أَبِي بُرْدَةَ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، أَنَّ النَّبِيَّ ﷺ بَعَثَ مُعَاذًا وَأَبَا مُوسَى إِلَى الْيَمَنِ قَالَ
" يَسِّرَا وَلاَ تُعَسِّرَا، وَبَشِّرَا وَلاَ تُنَفِّرَا، وَتَطَاوَعَا وَلاَ تَخْتَلِفَا ".
