The Results of Maintaining Ties of Kinship
Anas (radi Allahu anhu) reported that the Messenger of Allah (sal Allahu alaihi wa sallam) said, “He who desires ample provisions and his life prolonged, should maintain good ties with his blood relations.”
[Sahih al-Bukhari and Muslim]
One who is benevolent and compassionate towards one’s own relatives, stands to gain at least two definite advantages in this world besides the reward in the next. These two advantages are the increase in his subsistence and longevity of life.
Increase in subsistence means that Almighty Allah will increase the quantity of his worldly goods or his means of subsistence will be blessed by Him.
Similar is the case of longevity of life. The life of such person is either actually increased (in terms of years) or his life is graced with the Blessings of Allah. Both interpretations are correct.
And Allah Knows Best!
