question #1 Sahih Muslim 706b, Book 6, Hadith 63 : Why did the Prophet Muhammad (ﷺ) combine prayers during the expedition to Tabuk?

The Messenger of Allah (ﷺ) combined in the expedition to Tabuk the noon prayer with the afternoon prayer and the sunset prayer with the ‘Isha’ prayer. He (one of the narrators) said: What prompted him to do that? He (Mu’adh) replied that he (the Holy Prophet) wanted that his Ummah should not be put to (unnecessary) hardship.
