Maintain your ties of kinship. Keeping your social connections with relatives, and having a good social network contributes to longevity, an optimistic outlook and provides a good support mechanism in times of distress and hardship. This has an overall benefit to one's health.
Bukhari and Muslim relate from Anas ibn Malik who narrates: The Messenger of Allah (sallAllahu alayhi wa sallam) said, "Whoever wishes to have his sustenance increased and his length life prolonged should maintain the ties of kinship". And Abu Hurayrah reported: The Messenger of Allah (sallAllahu alayhi wa sallam) said, "Whoever is pleased to have his provision expanded and his length of life increased should maintain ties of kinship".
