Is it Permissible for a Mourner to Recite Taḥanun in the Afternoon Prayer?

Greetings,

One does not recite Taḥanun in the house of mourning for the entire week of shiva. However, when the mourner prays in a synagogue or another location, the congregation is not obliged to follow him, and they do recite Taḥanun, yet the mourner himself should not recite it.

Wishing you good tidings,
