question #1 Sahih Muslim 631a, Book 5, Hadith 263 : What actions did the Prophet Muhammad (ﷺ) take when he missed the ‘Asr prayer?

Messenger of Allah, by God, I could not say. the ‘Asr prayer till the sun set. Upon this the Messenger (ﷺ) said: By Allah I, too, have not observed it. So we went to a valley. The Messenger of Allah (ﷺ) performed ablution and we too performed ablution, and then the Messenger of Allah (ﷺ) said the ‘Asr prayer after the sun had set. and then said the evening prayer after it.
