وإن كنتم على سفر ولم تجدوا كاتبا فرهان مقبوضة فإن أمن بعضكم (2:283) بالانجليزي

(2:283) If you are on a journey and cannot find a scribe to write the document, then transact your business on the security of a pledge in hand. *331 And, if any one transacts a piece of business with another merely on trust, then the one who is trusted should fulfil his trust and fear Allah, his Lord And never conceal evidence *332 for he who conceals it, has a sinful heart: Allah knows everything that you do.

*331). This does not mean that pledge transactions are confined to journeys alone. These transactions have been specially mentioned in the context of journeys because during journeys people often have to resort to pledge transactions. Moreover, it has not been laid down that pledge transactions may be entered into only when a scribe is not available to write down the transaction. It is also permissible, if the lender is not satisfied merely with the written promise of the repayment of the loan, for the borrower to seek a loan by pledging some property to the lender. But since the Qur'an urges its followers to be generous in their dealings, and since it is inconsistent with high standards of moral excellence not to make loans to needy persons without keeping some property in custody, the Qur'an has abstained from mentioning this form of dealing even though it is permissible.
It should also be noted that the purpose of taking a pledge is merely to assure the lender the return of his loan. He has no right at all to benefit from the pledged property. If a person lives, say, either in the building which has been pledged, or pockets its rent, he is guilty of taking interest. There is no essential difference between charging interest directly and using the pledged property. If, however, either cattle or beasts of burden have been pledged, they can be milked and used for transport in lieu of the fodder that one provides them during the period of custody.
*332). Concealing true evidence applies both to a person not appearing to give evidence and to his avoidance of stating facts.
