Silsilat al-Ahadith al-Sahihah

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) came to a group of companions who were laughing and chatting. He (peace be upon him) said: "By the One in Whose hand is my soul! If you knew what I know, you would laugh little and weep much." Then he (peace be upon him) left, and the companions began to weep. Allah Almighty revealed to him: O Muhammad! Why are you making My servants despair? The Noble Prophet (peace and blessings be upon him) returned and said: "Rejoice, remain steadfast on the right path, and adopt moderation."
