قال محمد بن الحسن ما تضمن الخبر المتقدم من قوله بدا لله في محمد كما بدا له في إسماعيل معناه ظهر من الله وأمره في أخيه الحسن ما زال الريب والشك في إمامته، فإن جماعة من الشيعة كانوا يظنون أن الأمر في محمد من حيث كان الأكبر، كما كان يظن جماعة أن الأمر في إسماعيل بن جعفر دون موسى عليه السلام. فلما مات محمد ظهر من أمر الله فيه وأنه لم ينصبه إماما كما ظهر في إسماعيل مثل ذلك، لا أنه كان نص عليه ثم بدا له في النص على غيره فإن ذلك لا يجوز على الله تعالى العالم بالعواقب.
Muhammad bin Hasan [Shaykh Tusi] says: That which was mentioned in the previous report is based on the fact that change of destiny (Bada) occurred about Ismail as well as Muhammad. It means that with regard to the brother of Muhammad, Imam Hasan Askari 
, a new matter was revealed from Almighty Allah and this removed doubt about his Imamate, since some Shia thought that Imamate was fixed for Muhammad and he was the Imam, as he was elder to Imam Hasan Askari . They thought in the same way with regard to the Imamate of Ismail bin Ja’far and Imam Musa Kadhim not being the Imam. Hence when Muhammad died, the command of Allah was revealed about him; that is he is not the Imam and that he is not appointed to Imamate, and the same was revealed with regard to Ismail previously. Not that previously a text based on his Imamate was mentioned and after that Allah changed His decision in favor of someone; as such a thing is impossible from Almighty Allah and He is aware of the end of all matters.
