Hazrat Anas bin Malik (may Allah be pleased with him) reported that the Holy Prophet (peace and blessings of Allah be upon him) said:
يَسِّرُوا وَلَا تُعَسِّرُوا، وَبَشِّرُوا وَلَا تُنَفِّرُوا
“Make things easy and do not make them difficult. Give glad tidings and do not create aversion.”
[Sahih Bukhari, Hadith no. 69]
It was reported by Hazrat Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said:
مَنْ كَانَ يُؤْمِنُ بِاللّٰهِ وَالْيَوْمِ الآخِرِ فَلْيَقُلْ خَيْرًا أَوْ لِيَصْمُتْ وَمَنْ كَانَ يُؤْمِنُ بِاللّٰهِ وَالْيَوْمِ الآخِرِ فَلْيُكْرِمْ جَارَهُ وَمَنْ كَانَ يُؤْمِنُ بِاللّٰهِ وَالْيَوْمِ الآخِرِ فَلْيُكْرِمْ ضَيْفَهُ
“He who believes in Allah and the Last Day should either say what is good or else remain silent; and he who believes in Allah and the Last Day should respect his neighbour and he who believes in Allah and the Last Day should honour his guest.”
[Sahih Muslim, Hadith no. 47a]
