The Ruling on the First Tashahhud and How It Differs from the Last

Question:
And the Shaykh differed regarding the hadith "Or the chamber of your brother is a tent of hair," why? Because he used this as evidence for the obligation of the first tashahhud, just as he used it as evidence for the obligation of the common single hadiths, such as "And when he saw that the Messenger (peace and blessings be upon him) regretted it, he would stand up."

Answer:
The first tashahhud is not like the last tashahhud, as evidenced by the fact that when the Prophet (peace and blessings be upon him) stood up and forgot the first tashahhud, he did not return to it. If it had been a pillar, he would have returned to it. This indicates that it is not a pillar. Also, this is how it differs from the last tashahhud, because when the Messenger (peace and blessings be upon him) stood up and forgot the first tashahhud, he did not return to it; rather, he performed the two prostrations of forgetfulness. Yes.
