Give tidings (to the people) ; do not create (in their minds) aversion (towards religion) ; show them leniency and do not be hard upon them.

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا بَعَثَ أَحَدًا مِنْ أَصْحَابِهِ فِي بَعْضِ أَمْرِهِ قَالَ بَشِّرُوا وَلاَ تُنَفِّرُوا وَيَسِّرُوا وَلاَ تُعَسِّرُوا

Show leniency (to the people) ; don't be hard upon them; give them glad tidings (of Divine favours in this world and the Hereafter) ; and do not create aversion. Work in collaboration and don't be divided.

أَنَّ النَّبِيَّ ﷺ بَعَثَهُ وَمُعَاذًا إِلَى الْيَمَنِ فَقَالَ: «يَسِّرَا وَلاَ تُعَسِّرَا وَبَشِّرَا وَلاَ تُنَفِّرَا وَتَطَاوَعَا وَلاَ تَخْتَلِفَا

This hadith has been transmitted on the authority of Buraida but for the last two words.

عَنِ النَّبِيِّ ﷺ نَحْوَ حَدِيثِ شُعْبَةَ وَلَيْسَ فِي حَدِيثِ زَيْدِ بْنِ أَبِي أُنَيْسَةَ وَتَطَاوَعَا وَلاَ تَخْتَلِفَا

Show leniency; do not be hard; give solace and do not create aversion.

قَالَ رَسُولُ اللَّهِ ﷺ يَسِّرُوا وَلاَ تُعَسِّرُوا وَسَكِّنُوا وَلاَ تُنَفِّرُوا
