عن أنس بن مالك أن رسول الله صلى الله عليه وسلم قال: من أحب أن يبسط له في رزقه وينسأ له في أثره فليصل رحمه (صحيح البخاري الرقم: 5986)

Hazrat Anas bin Maalik (radhiyallahu ‘anhu) reports that Rasulullah (sallallahu ‘alaihi wasallam) said, “The one who wishes that his sustenance should be increased for him, and that his life should be lengthened for him, then he should maintain family ties.”

Note: The meaning of one’s life being lengthened is that Allah Ta‘ala will bless one with the tawfeeq of carrying out good actions in his lifetime which will continue to earn him great rewards for a long time after his demise.
