A:
Invoking blessings on the Prophet (peace be upon him) is obligatory after Tashahhud in the last Rak`ah (unit of prayer) of all Salahs. However, it is recommended to invoke blessings on the Prophet (peace be upon him) during the Tashahhud of the second Rak`ah of the Salahs consisting of three or four Rak`ahs after saying the Two Testimonies of Faith. This is based on the general meaning of the Hadith that enjoins invoking blessings on the Prophet (peace be upon him).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
