I say, and with God's success: It is recommended to say the name of Allah before entering the restroom; as he (peace be upon him) said: "The veil between the eyes of the jinn and the private parts of the children of Adam, when one of them enters the restroom, is to say: In the name of Allah." This is found in Sunan al-Tirmidhi 2/503, and al-Tirmidhi said: "This is a strange hadith, we do not know it except from this source, and its chain of narration is not that strong due to the weakness of Muhammad ibn Hamid al-Razi - and it has been narrated from Anas (may Allah be pleased with him) from the Prophet (peace be upon him) regarding this matter." And it is found in Sunan Ibn Majah 1/109, and in the Al-Mu'jam Al-Awsat 3/67, refer to: Al-Tawdiḥ Sharh Muqaddimah Abi al-Layth, and Allah knows best.
