Abdullah bin Abbas reported,

The Prophet ﷺ was being asked questions on the Day of Sacrifice at Mina, and he kept saying, "There is no harm."A man asked him, "I shaved my head before slaughtering."He replied, "Slaughter now, there is no harm."Another said, "I threw the pebbles after evening had come."He answered, "There is no harm."
