1 In what manner is a mourner forbidden to extend a greeting of peace? — [During] the first three days he does not extend a greeting of peace to anyone. If others were unaware that he is a mourner, and extended to him a greeting of peace, he should not respond to them, but should inform them that he is a mourner. After three and to seven [days] he does not extend a greeting [of peace]. If others were unaware that he is a mourner and extended to him a greeting of peace, he responds to them.. After seven [and] to thirty [days] he extends a greeting of peace to others who abide in peace, but others do not extend to him a greeting of peace, and so much the more that he responds to one who extended to him a greeting of peace. After thirty days he is regarded as all other people. This applies only in the case of other near-of-kin, but [one who is in mourning] for his father or mother, extends a greeting of peace to others after the seven [days of mourning], but others do not extend a greeting of peace to him until after twelve months. Rema: And since he is forbidden to extend a greeting of peace, so much the more is he forbidden to indulge in much conversation. However, if he does [ so ] out of deference to the public, e.g., if many [ people ] came to offer him consolation, he is permitted to say to them, 'Go to your homes unto peace,' — for out of deference to the public, it is permissible. There are some who adopt a lenient view nowadays with respect to extending a greeting of peace to the mourner after thirty days, and [ actually ] they have no grounds for this [ procedure ], unless [ it is possible ] that they make a distinctoin [ in this matter ] by saying that our custom [ today ] of extending [ a greeting to the mourner ] is not regarded [ on the same footing as ] a greeting of peace extended in their [ former ] days.
