question #1 Sahih Muslim 114, Book 1, Hadith 216 : What is the significance of honesty and integrity in handling war booty in Islam?

So and so is a martyr, till they happened to pass by a man and said: So and so is a martyr. Upon this the Messenger of Allah remarked: Nay, not so verily I have seen him in the Fire for the garment or cloak that he had stolen from the booty, Then the Messenger of Allah (ﷺ) said: Umar son of Khattab, go and announce to the people that none but the believers shall enter Paradise. He (‘Umar b. Khattab) narrated: I went out and proclaimed: Verily none but the believers would enter Paradise.
