The Prophet ﷺ said, "Facilitate things to people (concerning religious matters), and do not make it hard for them and give them good tidings and do not make them run away (from Islam).  

عَنِ النَّبِيِّ ﷺ قَالَ يَسِّرُوا وَلاَ تُعَسِّرُوا وَبَشِّرُوا وَلاَ تُنَفِّرُوا  

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."  

أَنَّ النَّبِيَّ ﷺ بَعَثَ مُعَاذًا وَأَبَا مُوسَى إِلَى الْيَمَنِ قَالَ يَسِّرَا وَلاَ تُعَسِّرَا وَبَشِّرَا وَلاَ تُنَفِّرَا وَتَطَاوَعَا وَلاَ تَخْتَلِفَا  

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  

The Prophet ﷺ said, "Facilitate things to people (concerning religious matters), and do not make it hard for them and give them good tidings and do not make them run away (from Islam). (Using translation from Bukhārī 69)   

وَقَالَ يَعْنِي رَسُولَ اللهِ ﷺ «يَسِّرُوا وَلَا تُعَسِّرُوا وَبَشِّرُوا وَلَا تُنَفِّرُوا»  

The Prophet ﷺ said, "Facilitate things to people (concerning religious matters), and do not make it hard for them and give them good tidings and do not make them run away (from Islam). (Using translation from Bukhārī 69)
