The Ruling on the Basmalah in Ablution and in Restrooms

Question:
The Basmalah, O Shaykh, what is its ruling, especially in ablution, and also the Basmalah in restrooms?

Answer:
The basmalah in wudu' is obligatory, as it is one of the obligations of wudu', based on the saying of the Messenger (peace and blessings be upon him): However, if by "restroom" you mean the area outside the place of relief, such as the external washing areas, there is no harm in that; one may mention the name of Allah. Yes.
