Hadith 5618
Iyas bin Salamah narrates from his father (Sayyiduna Salamah bin Akwa’ رضي الله عنه): One day, I was taking the Prophet Muhammad (ﷺ), Sayyiduna Hasan رضي الله عنه, and Sayyiduna Husayn رضي الله عنه, riding together on a mule, until I brought them into the chamber of the Prophet (ﷺ). (Of Sayyiduna Imam Hasan رضي الله عنه and Sayyiduna Imam Husayn رضي الله عنه), one was sitting in front of the Prophet Muhammad (ﷺ), and the other was sitting behind him.
