Some people among us in Egypt have become accustomed to swearing by the Prophet (peace and blessings be upon him) in their dealings, and the matter has become commonplace. So when I advised one of these people who swear by the Prophet (peace and blessings be upon him), he answered me that this is honoring the Prophet (peace and blessings be upon him) and that there is nothing wrong with it. What is the ruling in your view, O honorable Shaykh?

The questioner : Some people among us in Egypt have become accustomed to swearing by the Prophet (peace and blessings be upon him) in their dealings, and the matter has become commonplace. So when I advised one of these people who swear by the Prophet (peace and blessings be upon him), he answered me that this is honoring the Prophet (peace and blessings be upon him) and that there is nothing wrong with it. What is the legal ruling in your view, O honorable Shaykh Muhammad?

The Shaykh : Swearing by the Prophet (peace and blessings be upon him), or by any other of the exalted ones, or by the attribute of the Prophet (peace and blessings be upon him), or by any other of the created beings is forbidden; indeed, it is a type of shirk (associating partners with Allah). If someone swears by the Prophet (peace and blessings be upon him) and says, "By the Prophet," or "By the Messenger," or swears by the Ka'bah, or swears by Jibril, or by Israfil, or by anyone other than these, he has disobeyed Allah and His Messenger and fallen into shirk. The Prophet (peace and blessings be upon him) said: And he said: .
As for the statement of the one who swears by the Prophet (peace and blessings be upon him) that this is a form of honoring the Prophet (peace and blessings be upon him), our answer is to say: This type of honoring is what the Prophet (peace and blessings be upon him) forbade, and he clarified that it is a type of shirk. So honoring the Prophet (peace and blessings be upon him) is by staying away from this, because honoring the Prophet (peace and blessings be upon him) does not consist of disobeying the Prophet (peace and blessings be upon him). Rather, honoring the Prophet (peace and blessings be upon him) is by obeying his command and avoiding his prohibition. Just as obeying his command and avoiding his prohibition indicates love for him (peace and blessings be upon him). For this reason, Allah the Exalted said regarding a group who claimed to love Allah: So if you want to honor the Prophet (peace and blessings be upon him) with the honor he deserves (peace and blessings be upon him), then obey his command and avoid his prohibition in everything you say and do, and by that you will be one who honors the Messenger of Allah (peace and blessings be upon him).
So my advice to my brothers who frequently swear by other than Allah, indeed, who swear by other than Allah, is that they should fear Allah Mighty and Majestic, and that they should not swear by anyone other than Allah Blessed and Exalted, in obedience to the command of the Prophet (peace and blessings be upon him) in his saying: and in avoiding falling into shirk, which the saying of the Prophet (peace and blessings be upon him) indicated: .
