← Previous Hadith Who was Ka`b's guide when Ka`b turned blind: I heard Ka`b bin Malik narrating: When he remained behind (i.e. did not Join) the Prophet (ﷺ) in the Ghazwa of Tabuk. Ibn Bukair, in his narration stated that Ka`b said, " I witnessed the Al-`Aqaba pledge of allegiance at night with the Prophet (ﷺ) when we jointly agreed to support Islam with all our efforts I would not like to have attended the Badr battle instead of that 'Aqaba pledge although Badr is more well-known than it, amongst the people."
