32-23 Muhammad ibn Al-Hassan ibn Ahmad ibn al-Waleed - may God have Mercy upon him - narrated that Muhammad ibn Al-Hassan al-Saffar quoted on the authority of Ahmad ibn Muhammad ibn Isa, on the authorityof his father that Al-Husayn ibn Khalid asked Abil Hassan Ar-Ridha’ عليه السلام, “Why is it that the sins of one who goes on the Hajj pilgrimage are not recorded for four months?” Ar-Ridha’ عليه السلام replied, “It is because the Sublime God has forbidden the entry of the atheists into the Shrine for four months as He says, ‘Go ye, then, for four months, backwards and forwards, (as ye will), throughout the land…’ That is whenever one of the believers goes to visit the Holy House (of God), his sins will not be recorded for four months.”
