question #1 Sahih Muslim 705d, Book 6, Hadith 64 : Why did the Prophet combine the noon and afternoon prayers, as well as the sunset and ‘Isha’ prayers, in Medina?

” I said to Ibn ‘Abbas: What prompted him to do that? He said: So that his (Prophet’s) Ummah should not be put to (unnecessary) hardship.” And in the hadith transmitted by Mu’awiya (the words are):” It was said to Ibn ‘Abbas: What did he intend thereby? He said he wanted that his Ummah should not be put to unnecessary hardship.”
