Riyad as-Salihin, 317

Abu Hurairah (May Allah be pleased with him) reported:

The Prophet (ﷺ) said, "May he be disgraced! May he be disgraced! May he be disgraced, whose parents, one or both, attain old age during his life time, and he does not enter Jannah (by rendering being dutiful to them)". <b>[Muslim]</b>.

وعنه عن النبي صلى الله عليه وسلم قال‏:‏ ‏

‏ رغم أنف، ثم رغم أنف، ثم رغم أنف من أدرك أبويه عند الكبر، أحدهما أو كليهما، فلم يدخل الجنة‏

‏ ((رواه مسلم))

<b>Guidance from the Hadith:</b><br> 1) Dutifulness to parents is a great reason for entering Paradise.<br> 2) The parents in their old age are the neediest to dutifulness owing to their weakness. Showing dutifulness to them is realized by saying to them good words and treating them in a good way.<br> 3) Undutifulness to parents is a reason for entering Hell. So, one should beware of closing a door to Paradise that was opened to him, and from opening a door leading him to Hell.
