Is the Abrahamic prayer permissible before the final Tashahhud?

The wording and order of the legal invocations (adhkar) must be preserved. This is supported by the narration in Sahih Muslim from Ibn Abbas (may Allah be pleased with them both), who said that the Prophet (peace and blessings of Allah be upon him) used to teach them the Tashahhud just as he would teach them a surah from the Qur'an. This indicates the great care taken with its wording and order. Therefore, the Shafi'is and Hanbalis held that if someone recites the Salawat (Ibrahimiyyah prayer) before the Tashahhud, it is not considered valid, and it must be repeated after the Tashahhud, because the order is obligatory.
