Hameed bin Abi Hameed حميد بن أبي حميد الطويل · The Book of the Times (of Prayer)

"I heard the Messenger of Allah (ﷺ) say on the Minbar: 'Do not let the Bedouin make you change the name of your prayer; verily, it is 'Isha'.'"

"The Messenger of Allah (ﷺ) prayed Fajr on the day of Khaibar during the time it was still dark, when he was near the enemy. Then he attacked them and said: 'Allahu Akbar! Khaibar is destroyed!' Twice. 'Then, when it descends in their courtyard, evil will be the morning for those who had been warned!'" As-Saffat 37:177
