Salam aleikum could u please send me the proof that aisha r.a used to put one of her finger in the Mouth after prophet passed away when sahaba used to come to talk to her and ask about islam and rasoul Allah

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

We have not come across any basis (or proof) for this statement.

Knowing such a matter does not benefit in any way, and lacking knowledge about it does not harm.

It is better for one to ask about matters that lead to action, and about Islamic rulings that he needs to correct his faith, acts of worship, and his dealings (transactions).

Allah knows best.
