فضائل الأعمال الصالحة
Anas ibn Mālik (may Allah be pleased with him) reported: I heard the Messenger of Allah (may Allah's peace and blessings be upon him) say: "Whoever loves to have his sustenance expanded and his term of life prolonged should maintain ties of kinship."  
عن أنس بن مالك -رضي الله عنه- قال سمعت رسول الله -صلى الله عليه وسلم- يقول: «من أحبّ أن يُبْسَطَ عليه في رزقه، وأن يُنْسَأَ له في أَثَرِهِ؛ فَلْيَصِلْ رحمه».

شرح الحديث :


This Hadīth urges us to uphold our kinship ties and highlights some of the benefits of doing so, in addition to winning the pleasure of Allah, the Almighty. Maintaining ties of kinship is a cause for immediate rewards in worldly life, by the occurrence of pleasant things, like the expansion of sustenance and prolongation of lifespan. Some people may see the Hadīth, in its literal meaning, as contradicting with the verse that says: {But never will Allah delay a soul when its time has come} [Sūrat al-Munāfiqūn: 11]. Answering this, we say that someone’s lifespan is dependent on certain causes. Let us say, for example, that someone’s life is set to be 60 years, if he were to maintain the ties of kinship, and 40, if he were to cut them off. So, Allah will extend his life, if he maintains ties of kinship, beyond the period fixed in case he does not uphold them.
