If you are traveling, and no scribe is available, a bond shall be posted to guarantee repayment. If one is trusted in this manner, he shall return the bond when due, and he shall observe God his Lord. Do not withhold any testimony by concealing what you had witnessed. Anyone who withholds a testimony is sinful at heart. God is fully aware of everything you do.
