Al-Hasan narrated from Abu Hurairah that the Messenger of Allah (s.a.w) said:
Who will take these statements from me, so that he may act upon them, or teach one who will act upon them? So Abu Hurairah said: I said: 'I shall O Messenger of Allah!' So he (s.a.w) took my hand and enumerated five (things), he said: Be on guard against the unlawful and you shall be the most worshiping among the people, be satisfied with what Allah has alloted for you and you shall be the richest of the people, be kind to your neighbor and you shall be a believer, love for the people what you love for yourself and you shall be a Muslim. And do not laugh too much, for indeed increased laughter kills the heart.
