if ye be on a journey and cannot find a scribe then a pledge in hand . and if one of you entrusteth to another let him who is trusted deliver up that which is entrusted to him and let him observe his duty to allah his lord. hide not testimony. he who hideth it verily his heart is sinful. allah is aware of what ye 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
