Sunan Ibn Majah
حَدَّثَنَا مُحَمَّدُ بْنُ مُوسَى الْوَاسِطِيُّ، حَدَّثَنَا الْمُعَلَّى بْنُ عَبْدِ الرَّحْمَنِ، حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " الْحَسَنُ وَالْحُسَيْنُ سَيِّدَا شَبَابِ أَهْلِ الْجَنَّةِ وَأَبُوهُمَا خَيْرٌ مِنْهُمَا " .
It was narrated that Ibn 'Umar said: "The Messenger of Allah said: 'Hasan and Husain will be the leaders of the youth of Paradise, and their father is better than them."
