The Book of Virtue; Good Manners and Joining of the Ties of Relationship - كتاب البر والصلة والآداب
حدثني حرملة بن يحيى التجيبي، أخبرنا ابن وهب، أخبرني يونس، عن ابن شهاب، عن أنس بن مالك، قال سمعت رسول الله صلى الله عليه وسلم يقول " من سره أن يبسط عليه رزقه أو ينسأ في أثره فليصل رحمه " .
Anas b. Malik reported: I heard Allah's Messenger (may peace be upon him) as saying: He who is desirous that his means of sustenance should be expanded for him or his age may be lengthened, should join the tie of relationship.
