The Prophet (ﷺ) was asked (about rites of Hajj) on the day of stay at Mina. He said: No harm. A man asked him: I got myself shaved before I slaughtered. He said: Slaughter, there is no harm. He again asked: The evening came but I did not throw stones at the jamrah. He replied: Throw stones now ; there is no harm.
