When the Messenger of Allah (ﷺ) finished a prayer in which he had recited (the Quran) loudly, he asked: Did any of you recite along with me just now? A man replied: Yes, Messenger of Allah. He said: I am wondering what is the matter with me that I have been contended with reciting the Quran. He said: When the people heard that from the Messenger of Allah (ﷺ) they ceased reciting (the Quran) along with him at the prayers in which he recited aloud.

Abu Dawud said: This tradition reported by Ibn Ukaimah has also been narrated by Ma'mar, Yunus, and Usamah b. Zaid on the authority of al-Zuhri similar to the tradition of Malik.
Sunan Abi Dawud Book 2, Hadith 436
← Previous Hadith Makhul used to recite Surah al Fatihah al-kitab quietly in the prayer in which the imam recites the Quran loudly when he observes the period of silence. If he does not observe the period of silence, recite it before him(i.e before his recitation), or along with him or after him; do not give it up in any case.

Sunan Abi Dawud Book 2, Hadith 435 Next Hadith → The Messenger of Allah (ﷺ) led us in prayer, that was, we think, the dawn prayer, He further narrated this tradition up to the words “what is the matter with me that I have been contended with in (the recitation of ) the Quran.”

Abu Dawud said: Musaddad in his tradition said that Ma’mar said: The people ceased to recite (the Quran) at the prayer in which the Messenger of Allah (ﷺ) recited aloud. Ibn al-Sarh said in his version that Ma’mar reported from al-Zuhri on the authority of Abu Hurairah. Then the people ceased (to recite behind the imam). Another version says: Sufyan said: Al-Zuhri spoke a word that I could not hear. Then Ma’mar said: He said: Then people ceased (to recite the Quran)

Abu Dawud said: This tradition has been narrated by ‘Abd al-Raman b. Ishaq on the authority of al-Zuhri. This version ends at the words: “What is the matter with me that I am contended with in (the recitation of) the Quran. Al-Awza’i also narrated it on the authority of al-Zuhri. This version has: Al-Zuhri said: The Muslims took lesson from that and thenceforth they did not recite (the Quran) at the prayer in which he (the Prophet) recited aloud.

Abu Dawud said: I heard Muhammad b. Yaya b. Faris say: The words “the people ceased to recite (the Quran)” is a statement of al-zuhri.
