Let him be humbled into dust; let him be humbled into dust. It was said: Messenger of Allah, who is he? He said: He who sees either of his parents during their old age or he sees both of them, but he does not enter Paradise. (Using translation from Muslim 2551a)
عَنِ النَّبِيِّ ﷺ قَالَ رَغِمَ أَنْفُ ثُمَّ رَغِمَ أَنْفُ ثُمَّ رَغِمَ أَنْفُ رَجُلٍ أَدْرَكَ وَالِدَيْهِ أَحَدَهُمَا أَوْ كِلَيْهِمَا عِنْدَ الْكِبَرِ لَمْ يَدْخُلِ الْجَنَّةَ
