Is this wording for the Tashahhud correct: (All greetings, prayers and good things are for Allah. Peace be upon you, O Prophet, and Allah's mercy and blessings. Peace be upon us and upon the righteous servants of Allah. I bear witness that there is no god but Allah, He is alone, He has no partner, and I bear witness that Muhammad is His servant and His Messenger. O Allah, send prayers upon Muhammad and upon the family of Muhammad, as You sent prayers upon Abraham and upon the family of Abraham, indeed You are Praiseworthy and Glorious. And send blessings upon Muhammad and upon the family of Muhammad, as You sent blessings upon Abraham and upon the family of Abraham, indeed You are Praiseworthy and Glorious)?

The addition of "He is One, without partner" in Ibn Mas'ud's tashahhud is considered an anomaly by the majority of scholars, but it has been reported in other marfu' (elevated) and mawquf (stopped) hadiths, and some scholars have authenticated it. There is no harm in saying it; in fact, some have even gone as far as to consider it commendable. Ibn Umar and Aisha both affirmed this addition in their tashahhuds.

As for the formula of sending blessings upon the Prophet (peace be upon him), it is well-established, as in the hadith of Ka'b ibn Ujra: "O Allah, send prayers upon Muhammad and upon the family of Muhammad, as You sent prayers upon Ibrahim and upon the family of Ibrahim, verily You are Praiseworthy, Most Glorious. O Allah, send blessings upon Muhammad and upon the family of Muhammad, as You sent blessings upon Ibrahim and upon the family of Ibrahim, verily You are Praiseworthy, Most Glorious."
