Strive to be truthful in your speech as well as your actions .

This hadith is about the importance of being truthful and honest in our words and deeds. It was narrated by Abdullah bin Ka'b, who heard Ka'b bin Malik talking about the battle of Tabuk when he remained behind. In this hadith, Allah rewards those who are truthful and honest with His forgiveness. This is demonstrated through the verse from Quran 9:117-119 which states that Allah has forgiven the Prophet, Muhajirin, and be with those who are true in words and deeds. This hadith teaches us that we should always strive to be truthful in our speech as well as our actions so that we can receive Allah's mercy. We should also remember that even if we make mistakes or tell lies, Allah will forgive us if we sincerely repent for our sins.
