Muhammad bin Mansur bin Da'ud محمد بن منصور بن داود الطوسي · The Book of al-Bay'ah

"I said: 'O Messenger of Allah, they are saying that no one will enter Paradise except a Muhajir."' He said: "There is no more emigration (Hijrah) after the Conquest of Makkah, rather there is Jihad and intention. When you are called to moblize (for Jihad) then do so."

"We used to pledge to the Messenger of Allah to hear and obey, the he said: 'In as much as you can."'
