LOOK AFTER YOUR AGING PARENTS H 317 "May his nose be rubbed in the dust, may his nose be rubbed in the dust, may his nose be rubbed in the dust - those who find their parents, one or both, reaching old age (and do not serve them) and because of this do not enter Paradise." R 317 Muslim with a chain up to Abu Hurairah who related that the Prophet, praise and peace be upon him, said this.
317- وعنه ، عن النَّبيّ صلى الله عليه وآله وسلم ، قَالَ : "رغِم أنفُ ، ثُمَّ رَغِمَ أنْفُ ، ثُمَّ رَغِمَ أنْفُ مَنْ أدْرَكَ أبَويهِ عِنْدَ الكِبَرِ ، أَحَدهُما أَوْ كِليهمَا فَلَمْ يَدْخُلِ الجَنَّةَ" رواه مسلم .
