The Prophet ﷺ established a bond of brotherhood between Salman and Abu Darda. Salman visited Abu Darda one day and noticed that Umm Darda was wearing shabby, neglected clothing.He asked her, "What is the matter with you?"She replied, "Your brother Abu Darda has no interest in worldly things."When Abu Darda arrived, he prepared food for Salman and said, "Eat, for I am fasting."Salman said, "I will not eat until you eat."So Abu Darda ate. When night came, Abu Darda got up to pray.Salman said, "Sleep."So he slept. Then he got up again to pray, and Salman said, "Sleep."When the last part of the night came, Salman said, "Get up now."They both prayed, and Salman said to him, "Your Lord has a right over you, your soul has a right over you, and your family has a right over you. So give each one who has a right his due."Abu Darda went to the Prophet ﷺ and mentioned this to him, and the Prophet ﷺ said, "Salman has spoken the truth."
آخى النبي ﷺ بين سلمان وأبي الدرداء، فزار سلمان أبا الدرداء فرأى أم الدرداء متبذلة، فقال لها: ما شأنك؟ قالت: أخوك أبو الدرداء ليس له حاجة في الدنيا. فجاء أبو الدرداء فصنع له طعاما، فقال: كل فإني صائم. قال: ما أنا بآكل حتى تأكل. فأكل، فلما كان الليل ذهب أبو الدرداء يقوم، قال: نم، فنام، ثم ذهب يقوم فقال: نم. فلما كان آخر الليل قال سلمان: قم الآن. فصليا، فقال له سلمان: إن لربك عليك حقا، ولنفسك عليك حقا، ولأهلك عليك حقا، فأعط كل ذي حق حقه. فأتى النبي ﷺ فذكر ذلك له، فقال النبي ﷺ: صدق سلمان.
