if you are upon a journey and a scribe cannot be found then let pledges be taken. if any of you trusts another let the trusted deliver his trust and let him fear allah his lord. and you shall not conceal the testimony. he who conceals it his heart is sinful. allah has knowledge of what you do.
وإن كنتم على سفر ولم تجدوا كاتبا فرهان مقبوضة فإن أمن بعضكم بعضا فليؤد الذي اؤتمن أمانته وليتق الله ربه ولا تكتموا الشهادة ومن يكتمها فإنه آثم قلبه والله بما تعملون عليم
