The Prophet (ﷺ) made a bond of brotherhood between Salmân and Ad-Dardâ. ' Salmân paid a visit to Ad-Dardâ ' and found Umm Ad-Dardâ ' dressed in shabby clothes and asked her why she was in that state. She replied, "Your brother Ad-Dardâ ' is not interested in (the luxuries of) this world." In the meantime Ad-Dardâ came and prepared a meal for Salmân. Salmân requested Ad-Darda ' to eat (with him), but Ad-Dardâ ' said, "I am observing Șaum (fast)." Salmân said, I am not going to eat unless you eat." So, Ad-Dardâ ' ate (with Salmân). When it was night and (a part of the night passed), Ad-Darda ' got up (to offer the night prayer), but Salmân told him to sleep and Ad-Dardâ ' slept. After sometime Ad-Dardâ ' again got up but Salmân told him to sleep. When it was the last hours of the night, Salmân told him to get up then, and both of them offered the (prayer). Salmân told Ad-Dardâ, Your Lord has a right on you, your ownself has a right on you, and your family has a right on you; so you should give the rights of all those who has a right on you. Ad-Dardâ ' came to the Prophet (ﷺ) and narrated the whole story. The Prophet (ﷺ) said, "Salman has spoken the truth." [3:189-0.B]
