Is it permissible to send blessings upon the Prophet (peace and blessings be upon him) in the first tashahhud?

The questioner : The Ibrahimi prayer in the first rest of the four-rak'ah or three-rak'ah prayer, or the Ibrahimi prayer up to the end, or "I bear witness that there is no god but Allah, and I bear witness that Muhammad is His slave and His Messenger, O Allah, send blessings upon Muhammad"?

The Shaykh : There is no difference between the first tashahhud and the final tashahhud that is followed by the taslim, except that in the final tashahhud, it is obligatory to seek refuge from four things and then to supplicate with whatever one wishes. This is among the specific features of the final tashahhud. As for what comes before that, the first and final tashahhuds share the same requirements, meaning that the tashahhud is obligatory, and the complete, unabbreviated sending of blessings upon the Prophet (peace and blessings be upon him) is obligatory, and a brief supplication is obligatory, even if it is only saying, "O my Lord, forgive me, O my Lord, have mercy on me," and then one stands up. As for the final tashahhud, it is obligatory to seek refuge from the four things, then one chooses from supplications and prolongs the final sitting as much as one wishes. Indeed, he (peace be upon him) would make part of his final supplication . All of this is after seeking refuge from the four things. In which tashahhud? The final one.
