question #1 Sahih al-Bukhari 560, Book 9, Hadith 37 : What are the prescribed times for the five daily prayers in Islam?

The Prophet (ﷺ) used to pray the Zuhr at midday, and the `Asr at a time when the sun was still bright, the
Maghrib after sunset (at its stated time) and the `Isha at a variable time. Whenever he saw the people
assembled (for `Isha’ prayer) he would pray earlier and if the people delayed, he would delay the
prayer. And they or the Prophet (ﷺ) used to offer the Fajr Prayers when it still dark.
