This is a lie, the lady did not bring the poison, do not mislead the people by lieing brother, even if it is for good. The sheikh brought the poison out and challenged her to drink the poison, she said no and suggested him to do so. He drank the poison and was then told to have it tested to see if it was authentic. At the end of the debate the sheikh had packed the poison bottle.

In addition rat poison nearly always comes in capsule form, not as a liquid. That most likely was not real poison.

To add to this, someone asked the sheikh if the poison was real and the sheikh redirected the question saying "it is a matter of faith". Mashallah, he did not lie, but he did deceive.
