Who is the best friend of our prophet?

Abu Bakr: The Loyal Companion

Abu Bakr, a devoted friend and father-in-law of the Prophet Muhammad, is honored with the title al-Ṣiddīq (الصِّدِّيق), meaning 'the Veracious', among Sunni Muslims. He was born to Abu Quhafa and Umm al-Khayr from the Banu Taym tribe. Notably, Abu Bakr was one of the first individuals to embrace Islam and actively engaged in spreading the message of Islam to the polytheists.
