Narrated Anas bin Malik:
حَدَّثَنَا آدَمُ ، حَدَّثَنَا شُعْبَةُ ، عَنْ أَبِي التَّيَّاحِ ، قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ ـ رضى الله عنه ـ قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم " يَسِّرُوا وَلاَ تُعَسِّرُوا، وَسَكِّنُوا وَلاَ تُنَفِّرُوا " .
The Prophet (ﷺ) said, "Make things easy for the people, and do not make it difficult for them, and make them calm (with glad tidings) and do not repulse (them ).
