Al-Husayn ibn Said, from Safwan, who informed me: Musa ibn Bakr or Abdullah ibn al-Mughirah, from Talhah ibn Zayd, from Abu Abdillah عليه السلام, peace be upon him, from his father عليه السلام, peace be upon him: Imam al-Sadiq عليه السلام said: “Indeed, the Messenger of Allah سبحانه وتعالى, may Allah سبحانه وتعالى bless him and his family, prayed two rak’ahs for al-Istisqa (the prayer for rain), and He صلى الله عليه وعلى آله وسلم began with the prayer before the sermon. He صلى الله عليه وعلى آله وسلم pronounced takbir seven times and then five times, and He صلى الله عليه وعلى آله وسلم recited aloud.”
