Jibreel (May peace be upon him) benefits from the shower of the Holy Prophet's (Sallallahu alaihi wa sallam) shower of Mercy
Imam Qazi Iyaz (May Allah shower His mercy on him) writes in his magnum opus Asf Shifa, in the first chapter:
It has been narrated that the Holy Prophet (Sallallahu alaihi wa sallam) told Jibreel pbuh: Have you received anything from my special mercy? He said: Yes.I used to be frightened about my fate. Now I am content about it. Because of You, Allah Ta’ala said the following about me:
Who is Mighty and Strong (in Calling to the Truth, Preaching the faith in Messengership and Spiritual Competence, and) is held in extreme reverence and veneration (and splendour and glory) in the Presence of the Lord of the Throne. Surah Takveer (81:20)
Jibreel (May peace be upon him) is the Prophet's vizier in the spiritual world
Allah Ta’ala made Jibreel not only a servant of the Holy Prophet (Sallallahu alaihi wa sallam), but also His vizier in the spiritual world. Imam Hakim Neshapuri narrated a Hadith in this context on the standards of Imam Bukhari and Imam Muslim in his Mustadrak:
It has been narrated on the authority of Hadhrat Abu Saeed Khudri (May Allah be well pleased with him) that the Holy Prophet (Sallallahu alaihi wa sallam) said: Verily, I have 2 viziers in the spiritual world and 2 on the earth. In the spiritual worlds, my viziers are Jibreel and Mikail and among the inhabitants of earth, my 2 viziers are Abu Bakr and Umar.
This Hadith has been recorded in other compendiums of Hadith with a slight change of wording. Imam Hakim's Mustadrak mentions this Hadith at 2 places, Imam Tirmidhi’s, Jame' Tirmidhi, mentions this Hadith at 1 place, Imam Suyuti mentions this Hadith in his Jame' Ul Ahadith Wal Maraseel at five places, Kanzul Ummal mentions this Hadith at 4 places, Imam Nasai mentions this Hadith in his Fadhail-e-Sahabah at one place.
Hadhrat Shaykh Ul Islam Imam Muhammad Anwarullah Farooqui (May Allah Ta'ala shower His mercy on him) writes in the commentary of this Hadith: When 2 viziers among angels like Jibreel and Mikail are the Holy Prophet's (Sallallahu alaihi wa sallam) viziers in the heavens and 2 are on this earth, is there any doubt that the Holy Prophet (Sallallahu alaihi wa sallam) is the king of the higher and lower worlds?
