Swearing by Allah's Life

Q: Is it valid to swear by the Life of Allah saying, "By the Life of Allah"? Ibn Al-Qayyim mentioned this in a poem entitled "An-Nuniyyah As-Shafiyah Al-Kafiyah".

A: It is permissible for a Muslim to say, "By the Life of Allah." There is nothing wrong with this, as it involves swearing by an established Attribute of Allah. A Muslim may swear by any of the Names of Allah or His Attributes.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
