Hadith below is from Bukhari
Abu Juhayfa Wahb ibn ‘Abdullah said, “The Prophet, may Allah bless him and grant him peace, joined Salman and Abu’d-Darda’ together in brotherhood. Salman visited Abu’d-Darda’ and saw Umm ad-Darda’ poorly dressed and said to her, ‘What’s the matter with you?’ She said, ‘Your brother Abu’d-Darda’ has no need of this world.’ Abu’d-Darda’ came and made some food for him. Salman said, ‘Eat.’ He said, ‘I am fasting.’ Salman said, ‘I will not eat unless you eat.'” He said, “He ate. In the night, Abu’d-Darda’ went to stand in prayer and Salman said to him, ‘Sleep!’ and he slept. Then he got up again and Salman said, ‘Sleep!’ At the end of the night, Salman said, ‘Now get up and we will pray.’ Salman said to him, ‘Your Lord has rights over you and your self has rights over you, so give those with rights their due.’ Abu’d-Darda’ came to the Prophet, may Allah bless him and grant him peace, and mentioned this to him and the Prophet said, ‘Salman spoke the truth.'”
Islam is a Deen of moderation. Our lives have to be balanced.
