Increase in wealth and life
The Prophet (Salla Allahu Alaihi Wa Sallam) said "He who desires that his life be prolonged and he be granted more provisions and to protected from the evil end , then let him fear Allah and maintain good ties with kinship (relationship of womb i.e. parents, brothers, sisters etc)".
( Al Imam Al Bazar and Al Hakim)
The Prophet (Salla Allahu Alaihi Wa Sallam) said as reported by Anas (Radhiyallahu Anhu) "He who desires that he be granted more provisions and his life be prolonged should maintain good ties with his kinship" .
(Al Imam Al Bukhari)
Who is the best in maintaining ties of kinshipThe beat one most sincere and greater in maintaining ties, is the one who keeps good relations when he is abandoned and takes the initiative and is forgiving when they make mistakes; is kind to them when they harm and wrong him.
The messenger of Allah (Salla Allahu Alaihi Wa Sallam) said "The person who perfectly maintains the ties of kinship is not the one who does it because he get recompensed by his relatives but the one who truly maintains the bond of kinship is the one who persist in doing so, even though others have severed ties with him and abandon him".
(Al Bukhari)
And the opposite is also trueCutting relations with kinship is one of the great major sins and its punishment takes place in this life and in the hereafter.
The Prophet (Salla Allahu Alaihi Wa Sallam) said: "There is not a sin that is worse which Allah hastens the punishment for its commiter in this life and what he will have waiting for him in the hereafter for oppression and severing ties with kinship".
(Al Imam Abu Dawood and Tirmidhi)
And Allah says: "And those who break the covenant of Allah after its rectification and severed that which Allah has commanded to be joined, the bond of kinship that is, and work mischief in the land on them is the curse, and for them is the unhappy evil home, (i.e. hell)"
(Surah Ar-Raad: 25).
