Q: Is it permissible to swear by other than Allah?

A: It is not permissible to swear by other than Allah, for the Prophet (peace be upon him) said, Truly! Allah, the Exalted, forbids you to swear by your fathers. If someone has to take an oath, they should swear by Allah or be silent. This Hadith is agreed upon (narrated by Al-Bukhari and Muslim). In another narration by Abu Dawud and Al-Nasa'y, Abu Hurayrah (may Allah be pleased with him) narrated that the Prophet (peace be upon him) said, Do not swear by your fathers, nor by your mothers; and swear by Allah only when you are being truthful. Moreover, Abu Dawud and Al-Tirmidhy narrated with a Sahih (authentic) Isnad (chain of narrators) that the Prophet (peace be upon him) said, Anyone who swears by other than Allah has committed Kufr (disbelief) or Shirk (associating others with Allah in His Divinity or worship). May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
