question #2 Sahih Muslim 705d, Book 6, Hadith 64 : How does the concept of avoiding hardship for the Ummah influence Islamic practices and rulings?

” 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.”
