Is it permissible to raise the hands in supplication after the adhan?

Question:
May Allah reward you. The sender, Umm 'Abd al-Rahman from al-Madinah al-Munawwarah, sent a message containing several questions. In the first, she asks: Is it permissible to raise the hands in the supplication prescribed after finishing listening to the adhan, namely the supplication, "O Allah, Lord of this perfect call and the established prayer"?

Answer:
No, it is not permissible to raise the hands, because this is something that has not been transmitted. Rather, the Prophet (peace and blessings be upon him) prescribed for us to make this supplication after finishing the adhan and after following the mu'adhdhin, and he did not prescribe raising the hands in that. Yes.
