It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever performs Hajj in such a way that he does not approach his women and does not commit any sinful act, he will return to his home as (pure) as the day his mother gave birth to him."
