1) My question is the henna that we take on 7th muharram in Karbala was actually taken by whom from the house of Ahlubait (as)?
2) I have heard that Imam Hassan (as) has 2 sons . One was Hazrat Qasim (as) and second was Hassan e Musna. From both of them one was son in law of Imam Hussain (as) . It is so that Imam Hassan’s son was the really son in law of Imam Hussain (as)?
