The Messenger of Allah ﷺ said, "Hasan and Husayn are the masters of the youth of Paradise."
حدثنا أبو نعيم حدثنا سفيان عن يزيد بن أبي زياد عن عبد الرحمن بن أبي نعم
قال رسول الله ﷺ الحسن والحسين سيدا شباب أهل الجنة
Its isnad is sahih. Abu Naeem is Fadl bin Dukayn, the imam, and Yazid bin Abu Ziyad is the Hashimi Qurashi, their client. The hadith has already appeared at 10941.
