عن أبي هريرة رضي الله عنه قال: سمعت النبي صلى الله عليه وسلم يقول: «مَنْ حَجَّ لِلهِ فَلَمْ يَرْفُثْ وَلَمْ يَفْسُقْ رَجَعَ كَيَوْمِ وَلَدَتْهُ أُمُّهُ».
The Prophet (may Allah's peace and blessings be upon him) points out that whoever performs Hajj without engaging in sexual relations and obscene speech, or evil acts, he will return home sinless. Sinning also includes doing the things prohibited while being in ihram. If these things are avoided, he returns from Hajj with his sins forgiven, as a baby is born free from sin.
