“Abu Sa'eed reported that Gabriel came to the Prophet (sallaahu alaihi wasallam) and asked, "Muhammad, have you fallen ill?" He answered, "Yes." [Gabriel] said, "In the name of Allah, I exorcise you from everything that harms you; from every jealous soul and evil eye He will cure you; I invoke the name of Allah for you." [Al-Musnad; c.f. Sahih Muslim, no. 5425].
Is this conversation between Gabriel and Prophet Muhammad (sallaahu alaihi wasallam) mentioned in the Qur’an, or is it the indirect divine revelation (wahy) through angel Gabriel?
This is not mentioned in the Qur’an. The Prophet (ﷺ) received three types of revelation (wahy): Qur'an, Hadith Al-Qudsi and Hadith An-Nabawi. Revelation is not restricted to the Qur'an, so not everything revealed to him is found in the Qur’an. Allah says:
(وَمَا يَنطِقُ عَنِ ٱلۡهَوَىٰٓ (٣) إِنۡ هُوَ إِلَّا وَحۡىٌ۬ يُوحَىٰ (٤
“Nor does he speak from [his own] inclination. It is not but a revelation revealed.” 
This verse indicates that Hadiths are also revelation, and that it is not restricted to the Qur’an.
