It is narrated from Sayyiduna Wa'il bin Hujr (may Allah be pleased with him) that he prayed with the Prophet (peace and blessings be upon him). When he (peace and blessings be upon him) recited "Not of those who have earned Your anger, nor of those who go astray" [Surah al-Fatihah: 7] , he said "Amin" and kept his voice low with it. Qadi Isma'il said that in it the word is "ghayri" (with a kasrah under the ra'), because in the recitation of the people of Makkah it is read "ghayra" (with a fathah on the ra'). This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
