The ruling on the ma'mum raising his hands with the khatib during the supplication

The questioner:
Honorable Shaykh, may Allah grant you success. If the khatib raises his hands on Friday while making supplication, and the ma'mum raises his hands, is it prescribed for the ma'mum to raise his hands with the khatib?

The Shaykh:
What?

The questioner:
If the khatib raises his hands on Friday while making supplication, is it prescribed for the ma'mum to raise his hands like him?

The Shaykh:
It is not permissible for the imam or the ma'mum to raise their hands during the Friday sermon, except if he is making the supplication for rain. If he is making the supplication for rain, he raises his hands and those present raise their hands. This is specific to the supplication for rain in the Friday sermon. The Prophet (peace and blessings be upon him) raised his hands and the people raised their hands when he sought rain for them. As for supplication other than for rain, it is not permissible for the imam or the ma'mum. This is a bid'ah (religious innovation). Yes.
