18. Abu Ali al-Ash’ari has narrated from certain individuals of his people from ibn abu Najran from certain individuals of our people from abu ‘ Abd Allah who has said the following: “Once a Christian man sneezed in the presence of Abu ‘Abdillah and the people said, ‘May Allah guide you.’ Abu ‘Abd Allah said, ‘Say, “May Allah grant you mercy.’” They said, ‘He is a Christian.’ The Imam said, ‘Allah will not guide him until He grants him mercy.’”
