Abu Juhaifa reported: The Prophet, peace and blessings be upon him, made a fellowship between Salman and Abu Darda. Salman visited Abu Darda and found his wife Umm Darda dressed in worn-out clothing. He asked her why she was like this. She said, “Your brother Abu Darda is not interested in this world.” Then, Abu Darda entered and prepared a meal for Salman. Salman asked Abu Darda to eat with him, but he said, “I am fasting.” Salman said, “I will not eat until you eat.” So Abu Darda ate with him. When the night set in, Abu Darda stood for prayer, but Salman asked him to sleep, and Abu Darda slept. After a while, Abu Darda arose again, but Salman asked him to sleep. When it was the last hours of the night, Salman asked him to get up, and they both offered night prayers. Salman said to him, “Verily, you have a duty to your Lord, you have a duty to your body, and you have a duty to your family, so you should give each one its rights.” Abu Darda came to the Prophet and told him what had happened. The Prophet said, “Salman spoke the truth.”
