Sayyidah Aisha (may Allah be pleased with her) said that Muslim women used to come wrapped in their sheets to perform the Fajr prayer with the Messenger of Allah, and after finishing the prayer, when they returned to their homes, no one could recognize them because of the darkness.

Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) used to lead the Zuhr prayer exactly at midday when the sun was still clear and bright. He would lead the Asr prayer when the sun was still shining. He would offer the Maghrib prayer as soon as its time began. As for the Isha prayer, sometimes he would offer it early and sometimes late; when he saw that people had gathered, he would offer it early, and if people did not gather quickly, he would delay the prayer (and wait for the people). As for the Fajr prayer, the Companions or (he said that) the Prophet (peace and blessings be upon him) used to offer it in darkness.

Sayyiduna Abu Barzah Aslami رضي الله عنه was asked about the times of prayer, so he said that the Prophet صلى الله عليه وسلم used to perform the Zuhr prayer when the sun had declined. When he performed the Asr prayer, a person could go to the farthest edge of Madinah, but the sun would still be present. Regarding Maghrib, I do not remember what he said. And for Isha, he did not feel it wrong to delay it until a third of the night had passed, and he disliked sleeping before it and talking after it. When he finished the Fajr prayer, every person could recognize the one sitting next to him, and he would recite between sixty and a hundred verses in both rak‘ahs or in one of them.
