“Al-Hajjaj asked me about the Messenger of Allah’s mobilization for the wars in which he (a.s.), took part. I said, ‘The Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, mobilized for Badr with three hundred and thirteen people. He mobilized for Uhud with six hundred and for al-Khandaq (Battle of Ditches) with nine hundred people.’ He asked, ‘Who has said it?’ I replied, ‘Ja’far ibn Muhammad (a.s.) .’ He then said, ‘By Allah whoever adopts a way other than his way is lost.’”
