Supplication said after Tashahhud

Q 1: Is it an act of Sunnah (commendable act) or Wajib (obligatory) to make Du`a' (supplication to Allah) after invoking Allah's peace and blessings upon the Prophet (peace be upon him) during the first Tashahhud (testification recited in the sitting position in the second unit of Prayer)?

A: It is not an act of Sunnah to make Du`a' in the first Tashahhud. According to Hadiths narrated from the Prophet, it is an act of Sunnah to do this in the second Tashahhud after invoking Allah's peace and blessings upon the Prophet (peace be upon him).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
