Abu Hurayrah (may Allah be pleased with him) reported: When the Messenger of Allah (may Allah's peace and blessings be upon him) recited: ﴿...those who are neither subject to Your anger nor have gone astray.﴾ [Sūrat al-Fātihah: 7], he would say 'amen' until people in the first row behind him could hear it.
شرح الحديث :
It was from the Prophet's guidance to say 'amen' after reciting Sūrat al-Fātihah and to raise his voice so that his Companions would hear it. Saying 'Amen' is recommended. The Hadīth is weak; however, its meaning is supported by other authentic Hadīths. Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "When the Imām says 'amen', you too say 'Amen', for whoever says it at the same time as the angels say it, all his previous sins will be forgiven." Ibn Shihāb Az-Zhuhri said: "The Messenger of Allah (may Allah's peace and blessings be upon him) used to say 'amen.'"
