Answer: Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah’s peace and blessings be upon him) said: "Whoever performs Hajj for the sake of Allah, while abstaining from intercourse and foul language, will return (free from sins) as if he were born anew." [Narrated by Al-Bukhāri and others]

"As if he were born anew" means: free from sins.
