Hadith- The Hajj

In the Name of Allah, the Most Gracious, the Most Merciful.

Abu Hurayra said, "I heard the Messenger of Allah, may Allah bless him and grant him peace, say, 'Whoever goes on hajj for Allah alone and does not have sexual intercourse or commit any outrage will return as he was on the day his mother bore him.'" [Agreed upon]
