Sahih Bukhari | Volume 6 | Hadith Number 200

Narrated by 'Abdullah bin Kab
I heard Ka'b bin Malik talking about the story of the battle of Tabuk when he remained behind, "By Allah, I do not know anyone whom Allah has helped for telling the truth more than me since I mentioned that truth to Allah's Apostle till today, I have never intended to tell a lie. And Allah revealed to His Apostle: "Verily! Allah has forgiven the Prophet, the Muhajirin... and be with those who are true (in words and deeds)." (9:117- 119) (See Hadith No. 702 Vol 5).
