Make supplications whenever you hear mention of the Prophet's name.

This hadith encourages us to make du'a or supplications for the Prophet Muhammad (peace be upon him). Whenever his name is mentioned, we should take that opportunity to remember and honor him by making du'a. We should also remember that he was sent as a mercy and blessing from Allah to all of mankind, so we should thank Allah for sending such a great prophet. Additionally, this hadith reminds us of the importance of zikr or remembrance of Allah and His Messenger in our lives. By making du'a whenever we hear the name of the Prophet, it helps us stay connected with Him and His teachings even if we are not able to physically meet Him.
