In case you live some distance from your parents, might it be sufficient for a fellow Witness or a neighbor to drop by on a regular basis and then let one of the children know how the parents are doing?
فَفِي حَالِ كُنْتَ تَعِيشُ بَعِيدًا عَنْ مَكَانِ سُكْنَى وَالِدَيْكَ ،‏ فَهَلْ يَكْفِي أَنْ يَزُورَهُمَا أَحَدُ ٱلْإِخْوَةِ أَوْ أَحَدُ ٱلْجِيرَانِ بِشَكْلٍ مُنْتَظِمٍ وَيُعْلِمَكَ عَنْ حَالِهِمَا ؟‏
