Is it legally permissible to clap during prayer to inform someone calling the worshiper from inside the house, who cannot see them, of their presence?

It is prescribed for men to say "Subhanallah" (Tasbih) during prayer when there is a need, and this is specific to them, as the Prophet, peace and blessings be upon him, said: "Tasbih is for men, and clapping is for women."

It is permissible to say Tasbih with the intention of making others understand that the worshiper is in prayer, or that he wants someone who is waiting.

It is disliked to draw attention by clapping because it is specific to women.
