The Prophet ﷺ said: There are forty characteristics; the highest of them is to give a goat on loan (for benefiting from its milk). If any man carries out any of those characteristics with the hope of getting a reward and testifying to the promise for it, Allah will admit him to Paradise for it. Abu Dawud said: In the version of Musaddad, Hassan said: So we counted other characteristics than lending the goat: to return the greeting, to respond to sneezing, and remove things which cause annoyance to the people from their path, and similar other things. We could not reach fifteen characteristics.
