Hadith of Supplication: The Prophet’s supplication he taught to Mu’adh because he loved him

Mu’adh ibn Jabal reported: The Messenger of Allah, peace and blessings be upon him, took me by the hand and he said, “O Mu’adh, I swear by Allah that I love you. I swear by Allah that I love you.” And he said, “I advise you, O Mu’adh, not to forget supplicating after every prayer, saying: O Allah, help me to remember you, give thanks to you, and worship you in the best manner.”

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.”
