Al-Hasan and Al-Husayn are the masters of the youth of Paradise

The Prophet (may Allah's peace and blessings be upon him) informed that his two grandsons, Al-Hasan and Al-Husayn, the sons of ‘Ali ibn Abi Tālib and Fātimah, the Prophet's daughter (may Allah be pleased with them), are the masters of those who die young and enter Paradise in terms of virtue, or they are the masters of the youth of Paradise except for the prophets and the rightly-guided caliphs.
