Allâh سبحانه و تعالى says: ‘And when the Qur'ân is recited, listen to it attentively and remain silent, that you may receive mercy.’ (7:204)
Sayyiduna Abu Hurairah رضي الله عنه says, 'Rasulullah صلى الله عليه وسلم turned around after a salâh in which he had recited loudly. He enquired, "Has any one of you recited (behind me)?" A man replied, "I did." Rasulullah صلى الله عليه وسلم said, "I say: what is it with me? I am being contested for the Qur'ân." After the people heard this from Rasulullah صلى الله عليه وسلم they stopped reciting with him (behind him) in those salâh in which he would pray loudly.'
Sayyiduna Abu Hurairah رضي الله عنه reports that Rasulullah صلى الله عليه وسلم said, 'The Imam has been appointed so that he may be followed. Thus, when he says the takbeer, you say it also, and when he recites remain silent.'
Sayyiduna Abu Musa al Ash'ari رضي الله عنه says, 'Rasulullah صلى الله عليه وسلم taught us that "When you stand up for prayer one of you should lead the rest, and when the Imam recites remain silent."
Abu Wail رضي الله عنه reports that Sayyiduna Abdullah Ibn Mas'ud رضي الله عنه was asked about reciting behind the Imam. He replied, 'Remain silent for the recitation (of the Imam). For indeed there is a duty in salâh for which the Imam is sufficient for you.'
Nafi' رضي الله عنه reports that when Sayyiduna 'Abdullah ibn 'Umar رضي الله عنهما would be asked, 'Should one recite behind the Imam?" he would reply, 'When one of you prays behind the Imam then the Imam's recitation is sufficient for him. When he prays alone he should recite.' Nafi' رضي الله عنه adds, 'Abdullah ibn 'Umar رضي الله عنهما would not recite behind the Imam.'
Sayyiduna Jabir ibn Abdullah رضي الله عنه relates that Rasulullah صلى الله عليه وسلم said, 'One who prays behind an Imam, the recitation of the Imam is sufficient for him.'
The above hadeeth has also been reported from Rasulullah صلى الله عليه وسلم on the authority of the noble Sahâbah Anas, Abdullah bin Abbas, Abu Hurairah, Abu Saeed al Khudri, Abdullah bin Umar, Ali, and Abu al Dardaa  رضي الله عنهم أجمعين.
Ahadeeth such as those above stressing the obligation of Sűrah al Fâtihah are for the Imam or the individual, not the muqtadi. Imam Tirmidhi رحمه الله has quoted Imam Ahmad رحمه الله who commented on the above hadeeth (There is no salâh for one...) by saying 'This is if he is alone.'
Wahb bin Kaysan رضي الله عنه reports that he heard Sayyiduna Jabir ibn Abdullah رضي الله عنه say, 'He who prays one rak'ah in which he does not recite Sűrah al Fâtihah has in fact not prayed at all, unless he is behind an Imam.'
Not reciting surah fatiha behind the Imam in any salah is the view of Imam Abu Hanifah, Imam Abu Yusuf, Ibn Abi Layla, Sufyan al Thawri, Hasan bin Hayy, and their followers (رحمة الله عليهم). This is the most famous verdict of the Hanafi fiqh and it is also one of the narrations from Imam Muhammad ibn Hasan al-Shaibani (رحمه الله).
