Bukhari

Hadith Commentary:
Here as well, a statement of Allah regarding Khadijah radi Allahu anha has been narrated; this is the point of relevance to the chapter.
The virtue of Khadijah radi Allahu anha is established.
Khadijah bint Khuwaylid radi Allahu anha was a very wealthy and most noble woman of the Quraysh, who herself expressed interest in marrying the Prophet sallallahu alayhi wa sallam.
She had been a widow for some time, and afterwards, she lived with the Prophet sallallahu alayhi wa sallam with such loyalty and devotion that it is difficult to find an example like it.
At the age of 65, three years before the Hijrah of the Prophet sallallahu alayhi wa sallam, she passed away in the blessed month of Ramadan and was buried in the famous cemetery of Makkah, Jannat al-Mu'alla (Jihun).
The Prophet sallallahu alayhi wa sallam was deeply grieved by her separation.
Inna lillahi wa inna ilayhi raji'un.

Hadith Commentary:
➊
In this hadith, a statement of Allah Ta’ala is mentioned in favor of Sayyidah Khadijah radi Allahu anha, because Allah Ta’ala addressed Jibril alayhis salam and sent greetings and glad tidings to Sayyidah Khadijah radi Allahu anha.
This demonstrates the virtue of Sayyidah Khadijah radi Allahu anha, that Allah Ta’ala Himself sends greetings to the noble wife of the Messenger of Allah sallallahu alayhi wa sallam.

➋
In this hadith as well, a statement of Allah Ta’ala is mentioned which pertains to His will (mashi’ah): Allah Ta’ala honors whomever He wills with His speech, and this speech is other than the Qur’an and is uncreated (ghayr makhluq).
And this is the intended point.
