The Messenger of Allah ﷺ passed by a man who was praying the two units before dawn while the congregational prayer had already begun. He said something to him that we could not make out. When we finished, we gathered around the man asking, "What did the Messenger of Allah ﷺ say to you?"He replied, "He said to me, 'One of you is about to pray the dawn prayer as four units.'"
