Sunan Ibn Majah 2089
It was narrated from 'Abdur-Rahman that:
a man's father or mother - Shu'bah (one of the namators) was not sure - ordered him to divorce his wife, and he made a vow that he would free one hundred slaves if he did that. He came to Abu Darda' while he was praying the Duha, and he was making his prayer lengthy, and he prayed between Zuhr and 'Asr. Then he asked him and Abu Darda' said: "Fulfill your vow and honor your parents." Abu Ad-Darda' said: "I heard the Messenger of Allah (ﷺ) say: '(Honoring) one's father may lead one to enter through the best of the gates of Paradise; so take care of your parents, (it is so, whether you take care of them) or not. "
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ عَطَاءِ بْنِ السَّائِبِ، عَنْ أَبِي عَبْدِ الرَّحْمَنِ، أَنَّ رَجُلاً، أَمَرَهُ أَبُوهُ أَوْ أُمُّهُ - شَكَّ شُعْبَةُ - أَنْ يُطَلِّقَ، امْرَأَتَهُ فَجَعَلَ عَلَيْهِ مِائَةَ مُحَرَّرٍ ‏.‏ فَأَتَى أَبَا الدَّرْدَاءِ فَإِذَا هُوَ يُصَلِّي الضُّحَى وَيُطِيلُهَا وَصَلَّى مَا بَيْنَ الظُّهْرِ وَالْعَصْرِ فَسَأَلَهُ فَقَالَ أَبُو الدَّرْدَاءِ أَوْفِ بِنَذْرِكَ وَبَرَّ وَالِدَيْكَ ‏.‏ وَقَالَ أَبُو الدَّرْدَاءِ سَمِعْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ يَقُولُ ‏
"‏ الْوَالِدُ أَوْسَطُ أَبْوَابِ الْجَنَّةِ فَحَافِظْ عَلَى وَالِدَيْكَ أَوِ اتْرُكْ ‏"‏ ‏.‏
