SHAFAQNA – Lady Hakimah the daughter of Imam Mosa Kazim (AS) and the sister of Imam Reza (AS) narrated: At the time of the birth of Imam jawad (AS), Imam Reza (AS) called me and said: O’ Hakimah, at the time of the birth of Imam Jawad (AS) be with the mother of the child, and after the birth, Imam Reza (AS) told me: O’ Hakimah, take care and stay near the child’s bed. Lady Hakimah added: On the third day after his birth, I saw Imam Jawad (AS), opened his eyes and looked towards the sky, then looked at his left and right and said: I witness that there is no God except Allah (SWT) and I witness that Mohammad (PBUH) is God’s Prophet.
By seeing this scene, I panicked and stood up, went to Imam Reza (AS) in a hurry and said: I just saw and heard surprising things from this innocent child. Imam Reza (AS) said: What surprising things you saw? I described all the things I saw for Imam (AS). Imam Reza (AS) said: O’ Hakimah, after this time, you will see more amazing and surprising things from him .
