What are the limits of maintaining kinship ties that necessitate visiting paternal and maternal cousins, and am I obligated to do so even if there is no harm in visiting them?

The paternal uncle's daughter and the maternal uncle's daughter are among the kin whose ties must be maintained. Islamic law has not specified a particular measure for maintaining these ties; rather, the customary practice is the reference point for this. Therefore, if refraining from visiting them is considered a severance of ties, then visiting them becomes obligatory, provided that no religiously forbidden act results from the visit, such as seclusion with a non-mahram, impermissible gazing, ostentatious display, or touching.
