Shia reports explain why Imamah was taken away from progeny of Hassan

[MuslimK]

Twelver Shia reports explain why Imamah was taken away from progeny of Hassan and restricted to progeny of Husayn.

What did Hassan do wrong? Well, his progeny was deprived of Imamah because of his peace with Muawiyah.

Keep in mind that al-Kulayni narrated the same report in his al-Kafi but had to tamper with the report as it was in conflict with his ideology.
