Is it permissible to take an oath in the name of the Holy Prophet (sa) or the Promised Messiah (as)?

Someone from Jordan sent the following questions to Hazrat Amirul Momineen, Khalifatul Masih V^aa:

1. Is everything out of sight a jinn and can Iblis and angels also be jinn?
2. Do Ahmadis believe in the existence of ‘ifrit?
3. We have read that the Promised Mahdi will appear in the Latter Days, are we really living in the Latter Days?
4. Can we take an oath in the name of Allah Almighty or the Holy Prophet^sa or the Promised Messiah^as?

Huzoor-e-Anwar, in his letter dated 10 February 2022, provided the following response to these queries:

“[…] As for the matter of taking an oath, one should not take oaths without a valid reason. If there is a need and the person taking the oath is on the side of truth, he can only take an oath by God Almighty. It is not permissible for a person to take an oath by another person. Hazrat Abu Hurairah^ra narrated that the Holy Prophet^sa said:

لَا تَحْلِفُوا بِآبَائِكُمْ وَلَا بِأُمَّهَاتِكُمْ وَلَا بِالْأَنْدَادِ وَلَا تَحْلِفُوا إِلَّا بِاللَّهِ وَلَا تَحْلِفُوا بِاللَّهِ إِلَّا وَأَنْتُمْ صَادِقُونَ

“‘Do not swear by your fathers, or by your mothers, or by idols; and swear by Allah only if you are truthful.’ (Sunan Abi Dawud, Kitab al-imani wa n-nudhur)”
