What is the fatwa-endorsed opinion regarding the obligation of maintaining kinship ties with mahram and non-mahram relatives? And is it obligatory to communicate with non-mahram relatives? What is the order of relatives in Islam after parents and siblings?

Kinship (Rahim) is divided into two types: Rahim Mahram (unmarriageable kin), which includes all those between whom marriage is impermissible, such as fathers and mothers; and Rahim Ghayr Mahram (marriageable kin), such as a paternal cousin or a maternal aunt's daughter. Scholars have differed on the obligation of maintaining ties with Rahim Ghayr Mahram. The more cautious opinion is that it is obligatory to maintain ties with all kin, both mahram and ghayr mahram.

The regulations of Islamic law must be observed when maintaining ties with Rahim Ghayr Mahram, such as a paternal cousin's daughter. She is considered a non-mahram, and therefore it is not permissible to shake hands with her, be in seclusion with her, or gaze at her. Connecting with her should be through greetings, asking about her well-being, or regulated phone calls, or financial assistance if she is poor. Similarly, for a woman with her paternal and maternal cousins, connecting with them should be by inquiring about them while observing hijab and ensuring there is no temptation.

Maintaining kinship ties has various degrees, the lowest of which is refraining from abandoning them and exchanging greetings. General kinship (rahim al-din - brotherhood in faith) necessitates adherence through faith, love, and support. Special kinship (rahim al-qarabah - blood relatives) entails specific rights such as financial support and checking on their circumstances.
