but Salmān said, “Go back to sleep.” When the last part of the night arrived Salmān said, “Now get up.” So we prayed together. Then Salmān said to him, “Your Lord has a right over you, your own self has a right over you, and your family has a right over you; therefore give each one who has a right his due.” Abū al-Dardāʾ then went to the Prophet ﷺ and reported this to him, and the Prophet ﷺ said, “Salmān has spoken the truth.” Recorded by al-Bukhārī.

[Explanation]
The author—may Allah have mercy on him—relates from Abū Juḥayfah Wahb ibn ʿAbd Allāh that the Prophet ﷺ forged a bond of brotherhood between Salmān and Abū al-Dardāʾ, may Allah be pleased with them both. “He joined them as brothers” means he established a formal tie of brotherhood between them. When the Emigrants first arrived in Medina, the Prophet ﷺ paired each of them with one of the Helpers, those who had settled the city and embraced faith before them. Through this pact the Emigrants stood to the Helpers as real brothers—even to the point that they inherited from one another—until Allah revealed: “Blood relatives are more entitled to one another in the Book of Allah” (al-Anfāl 8:75).

On one occasion Salmān entered the house of his brother Abū al-Dardāʾ—may Allah be pleased with him—and found Abū al-Dardāʾ’s wife looking unkempt; that is, she was not dressed as a married woman normally would, but wore plain clothes that were not attractive. He asked her, “What is the matter with you?” She answered, “Your brother Abū al-Dardāʾ has no concern for worldly life,” meaning he has turned away from worldly matters, from his wife, from food, and from everything else.
