Hadith 3
Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said:
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
Be devout and you will be the most pious of people. Be content and you will be the most grateful of people. Love for people what you love for yourself and you will be a believer. Behave well with your neighbors and you will be a Muslim. Laugh less, for too much laughter will deaden the heart.
