Ka'b offers his wealth and vows to speak only the truth

Ka'b offered his wealth in charity; the Prophet ordered him to keep part of it, so he kept his share of Khaybar and vowed to speak only truth for the rest of his life. ¹

Ka'b said: Messenger of God, part of my repentance to God is that I divest myself of my wealth as charity to God and His Messenger. The Prophet said: "keep part of your wealth — it is better for you." ²

He said: then I keep my share at Khaybar. And he said that God saved him through truthfulness, and part of his repentance was to speak nothing but truth as long as he lived. ²

Ka'b said he knew no one God had tried in truthfulness of speech better than He had tried him, and that he had not deliberately lied since he said that — and he hoped God would preserve him for what remained. ³

He said God had not blessed him, after guiding him to Islam, with a blessing greater in his eyes than his truthfulness to the Prophet that day — that he did not lie to him and perish as those who lied perished. ³

• In manuscript (a) "as long as I remain" appears instead of "as long as I live", per the editors (p. 180 n. 1).
• The phrase "as those who lied perished" is Ka'b's words, not the museum's.
