Is visiting the father's relatives obligatory for his children and his wife after divorce if they were the cause of it and did not reconcile the two parties?

The Shari'ah encourages affection and love among Muslims, which is a great blessing, especially among relatives whose ties must be maintained and whose severance is forbidden. It is obligatory for a sane, mature person to maintain ties of kinship; if they do not, they are sinful. If you are prevented from visiting, then maintaining ties is obligatory by whatever means are customarily possible. It is advisable to strive for reconciliation as much as possible, whether between parents or among relatives, for reconciliation is good, and mending relations between people is better than the rank of fasting, prayer, and charity, while corrupted relations between people are a razor that destroys religion.
