Abu Sa’eed Khudri رضي الله عنه narrates:
Nabi صلي الله عليه وسلم said:
“Every Nabi had two ministers/advisers in the sky and two ministers/advisers on earth.
My advisers in the sky are Jibril and Mikail (عليهما السلام) and my advisers on earth are Abu Bakr and ‘Umar”(رضي الله عنهما)
(Sunan Tirmidhi, Hadith: 3680)
