Whence came PBUH?

The phrase "Peace Be Upon Him" (PBUH) is a respectful expression used by Muslims when mentioning the name of the Prophet Muhammad ﷺ. This practice is deeply rooted in Islamic tradition and is supported by the Qur'an and hadith.

In the Qur'an, it is stated: Lo! Allah and His angels shower blessings on the Prophet. O ye who believe! Ask blessings on him and salute him with a worthy salutation. 33:56. This verse emphasizes the importance of sending blessings upon the Prophet, which is a form of respect and honor.

Additionally, it is narrated in hadith that the Prophet Muhammad ﷺ himself encouraged his followers to send blessings upon him. Although I do not have a specific hadith from Sahih Muslim to cite, it is well-known in Islamic tradition that this practice is emphasized throughout various collections of hadith.

Thus, saying PBUH after mentioning the Prophet's name is a way for Muslims to show their respect and love for him, following the guidance provided in the Qur'an and the teachings of the Prophet himself.
