117 - Chapter: What has been reported concerning recitation behind the Imam

311 - Hannād narrated to us, saying: ʿAbdah ibn Sulaymān narrated to us, from Muḥammad ibn Isḥāq, from Makḥūl, from Maḥmūd ibn al-Rabīʿ,
from ʿUbādah ibn al-Ṣāmit, who said: The Messenger of Allah, peace and blessings be upon him, prayed the morning prayer, and the recitation became heavy upon him. When he finished, he said: "I see that you recite behind your Imam." We said: O Messenger of Allah, yes, by Allah. He said: "Do not do so, except with the Mother of the Qurʾān, for there is no prayer for the one who does not recite it." (2)

It is corroborated by the ḥadīth of a man from among the companions of the Prophet, peace and blessings be upon him, in al-Musnad (18070), and its chain is ṣaḥīḥ.
And the ḥadīth of Abū Qatādah according to Aḥmad (22625), but in its chain there is a discontinuity.
Al-Baghawī said in Sharḥ al-Sunnah 3/84-86: The people of knowledge among the Companions, the Successors, and those after them differed concerning recitation behind the Imam. A group held it to be obligatory, whether the Imam recites aloud or silently; this is related from ʿUmar, ʿUthmān, ʿAlī, Ibn ʿAbbās, and Muʿādh, =
