Q: There are young men here
who swear by the words: "Exalted is He whose Eyes do not sleep". Is this a permissible oath?
These young men link the Attribute of not being liable to sleep with the Eye of the Creator (Glorified and Exalted be He). Allah did not tell us that. All that is mentioned in the Qur'an is His saying:
Neither slumber nor sleep overtakes Him.
A:
Saying: "Exalted is He Whose Eyes do not sleep" or "By Allah Whose Eyes do not sleep" is permissible. It is an Attribute of perfection. Allah says in the Qur'an:
...in order that you may be brought up under My Eye.
According to the Qur'an, Allah is neither overtaken by drowsiness nor sleep. It was reported in the authentic Sunnah that Allah does not sleep and He is not liable to sleep.
Moreover, the saying: "Exalted is He Whose Eyes do not sleep," is not an oath.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
