The authenticity of the hadith regarding the splitting of the Prophet's (peace and blessings be upon him) chest

Question:
He says: Honorable Shaykh, I read about the hadith of the splitting of the chest of the Messenger of Allah (peace and blessings be upon him) when he was young. How authentic is that? May Allah reward you.

Answer:
This is authentic. Allah (Mighty and Majestic) said: in Surat al-Nasr and Surat al-Sharh. This is authentic and it happened to the Messenger of Allah (peace and blessings be upon him). This is among his miracles, among his karamahs (miracles granted to a righteous person) (peace and blessings be upon him), and among the signs (irhasat) before the mission. They call these signs the pre-mission signs, which are supernatural events (kharq al-'adat) called the sign of the mission, such as the incident of the elephant, and such as the good supernatural events that occurred to him (peace and blessings be upon him) before his mission, which are called the sign (irhas) of his mission (peace and blessings be upon him). Among these is the splitting of his chest (peace and blessings be upon him). So it was a physical splitting, and there is also a spiritual splitting, which is the expansion of the chest, , the expansion of the chest for the remembrance of Allah and the love of the remembrance of Allah. This is a spiritual expansion. And what happened to the Messenger of Allah (peace and blessings be upon him) was both a physical and a spiritual expansion. Yes.
