The Prayer upon the Prophet (peace and blessings be upon him) in the Obligatory and Voluntary Prayers

Q: If a person passes by a verse in the prayer that mentions the Prophet (peace and blessings be upon him), should he pray upon him on the occasion of his mention, acting in accordance with the hadith: that the Messenger (peace and blessings be upon him) ascended the pulpit and said: three times, and it was said to him: You ascended the pulpit and said: Amen, Amen, Amen. He said: ... until he said: to the end of the hadith, or is the prayer upon him not among the acts of the prayer except in its place in the tashahhud, so it is not done except there, and as for elsewhere, it is not done?

A: As for the obligatory prayer, he does not do that because it was not transmitted from the Prophet (peace and blessings be upon him). As for the voluntary prayer, there is no harm in it, because he (peace and blessings be upon him) in his tahajjud at night would stop at every verse containing glorification and glorify, at every verse containing seeking refuge and seek refuge, and at every verse containing asking and ask.
And the prayer upon him (peace and blessings be upon him) is of this category. And Allah is the guarantor of success.
