Hadith on Asceticism: Love good for people, be content with Islam, be a good neighbor, and laugh less

Abu Huraira reported: The Messenger of Allah, peace be upon him, said, “O Abu Huraira, be cautious and you will be the most devoted of the people. Be content and you will be the most grateful of the people. Love for the people what you love for yourself and you will be a believer. Behave well with your neighbors and you will be a Muslim; and laugh less, for verily, too much laughter will deaden the heart.”

[Sunan Ibn Majah, Book of Asceticism, Number 4217, Da'eef]

عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَا أَبَا هُرَيْرَةَ كُنْ وَرِعًا تَكُنْ أَعْبَدَ النَّاسِ وَكُنْ قَنِعًا تَكُنْ أَشْكَرَ النَّاسِ وَأَحِبَّ لِلنَّاسِ مَا تُحِبُّ لِنَفْسِكَ تَكُنْ مُؤْمِنًا وَأَحْسِنْ جِوَارَ مَنْ جَاوَرَكَ تَكُنْ مُسْلِمًا وَأَقِلَّ الضَّحِكَ فَإِنَّ كَثْرَةَ الضَّحِكِ تُمِيتُ الْقَلْبَ

سنن ابن ماجه كِتَاب الزُّهْدِ كن ورعا تكن أعبد الناس وكن قنعا تكن أشكر الناس
