Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah (ﷺ) said, "Whoever performs Hajj (pilgrimage) and does not have sexual relations (with his wife), nor commits sin, nor disputes unjustly (during Hajj), then he returns from Hajj as pure and free from sins as on the day on which his mother gave birth to him."[Al-Bukhari and Muslim].
