ما هي حدود زيارة ابن الأخ أو الأخت الشاب لخاله أو عمته اللذين لديهما بنات، وما حكم مبيته الطويل عندهم؟

The maternal uncle and paternal aunt are considered kin whose ties must be maintained, by scholarly consensus. This involves showing kindness to them through financial support, visits, services, and similar actions. There is no objection to visiting them and staying overnight, even if they have daughters, provided there is no mixing with or privacy with these daughters, as they are not maharim (unmarriageable kin).
