أتاني جِبْرِيلُ فَبَشَّرَني أنَّ الحَسَنَ والحُسَيْنَ سَيِّدَا شَبَابِ أهْلِ الجَنَّةِ
(ابن سعد) عن حذيفة.)
It is reported that the Messenger of Allah, peace and blessings of Allah be upon him, said:
“Jibril appeared to me and delighted me with the news that al-Hassan and al-Husayn were leaders of the youth from among the inhabitants of paradise.” This hadeeth was narrated by Ibn Sa’d from the words of Husayfah.
Sheikh al-Albani called the hadith authentic. See “Sahih al-jami ‘as-sagir” 63, al-Silsila as sahiha 796.
