Is it permissible for a husband to maintain ties with his female paternal and maternal cousins (daughters of his paternal uncle, paternal aunt, maternal uncle, and maternal aunt) after the death of his parents, based on the hadith, "Indeed, among the dutifulness to one's parents after their death is to maintain ties with those whom they used to maintain ties with"?

Among the acts of filial piety towards parents after their death is maintaining ties with their loved ones and those they cherished, whether relatives or others. This is based on the Prophet's (peace be upon him) saying: "Indeed, the most virtuous act of piety is for a man to maintain ties with his father's loved ones after his passing." However, Islamic legal guidelines must be observed in these connections. If the person being connected with is a non-mahram (definition) woman, then the individual must adhere to the Islamic legal guidelines, such as connecting with paternal or maternal female cousins. They are part of the kinship ties that should be maintained and not severed, whether during the parents' lifetime or after their death.
