Reward of the Martyred Companions
قال الرضا (ع):
إن سرَّك أن يكون لك من الثواب مِثلُ ما لمَن استُشهد مع الحُسين فقُل متى ما ذكرته يا ليتني كُنت معهم فأفوز فوزاً عظيما

Imam Ridha’ (A.S.) said (to one of his companions): If you desire that for you be the reward equivalent to that of those martyred along with Husayn (A.S.), then whenever you remember him say: ‘ Oh! Would that I had been with them! A great achievement would I have achieved’.
