The Du‘a’ said in Tashahhud is authentically reported in many Hadiths, such as that narrated on the authority of
Ibn Mas‘ud and
Ibn `Abbas. You should adhere to the formula, which was reported in these Hadiths only; no other formula of Tashahhud can serve in its place, (Part No. 5; Page No. 370) for it is the one that the Prophet (peace be upon him) taught his Sahabah (Companions of the Prophet) same as he taught them the Surahs (Qur’anic chapters).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
