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 and does not commit obscenity or commit any evil therein will go back (free of sin) as on the day his mother gave birth to him."
‘Ā'ishah (may Allah be pleased with her) reported that the Prophet (may Allah's peace and blessings be upon him) said: "There is no day on which Allah sets free more of His slaves from Fire than the Day of ‘Arafah. He verily draws near, then He boasts about them before the angels saying: What do these people want?"
