As for the right which will become due later, as for example when a man says to a woman: ‘Marry this person and I guarantee your dowry’, the guarantor has joined his responsibility to the responsibility of the person guaranteed for such that the guarantor will be bound like the guaranteed for, and that which is proved in the responsibility of the guaranteed for is similarly proved in the guarantor’s responsibility.Whereas, if there is no right due upon anyone or a right that will become due later, then there is no meaning to the guarantee as there is no joining of responsibilities; such a guarantee therefore is not valid. Therefore, if the right was not due upon the neck of the person guaranteed for or it does not become due later, the guarantee is not valid. This is because it is a condition that the person guaranteed for has a guarantor for an object if it is damaged or destroyed, or He is responsible for a debt whether the matter is actual in the case where the right was due and proved to be his responsibility or He is potentially responsible in the case where the right will become due later. So, if the person guaranteed for was not responsible, whether immediately or potentially, the guarantee is invalid because whatever is not due upon the person guaranteed for is not due upon the guarantor. So, for example, in the case of a person who receives clothes from (e.g. cleaner), and somebody told another person: ‘Send your clothes to Him and I will guarantee them.’ If the clothes were then damaged, would the guarantor be responsible for the price of the clothes on behalf of the person who received them? The answer is as follows: If the clothes were damaged without his (i.e. the cleaner’s) action or negligence, then the guarantor guarantees nothing because, in the first place, the person guaranteed for (the cleaner) bears no responsibility for the damage. Since the principal (Aseel) is not liable for the damage then, with greater reason, neither is the guarantor. Therefore, there should be a right due to the person guaranteed for from other people, or it will become due later, in order that the guarantee becomes valid. So establishing the right for the person guaranteed for, whether immediately or potentially, is a condition for the validity of the guarantee. However, it is not a condition that the person guaranteed for (Madhmoon ‘Anhu) nor the guaranteed person (Madhmoon Lahu) be named; thus the guarantee will be valid if these were unknown (i.e. not named). So if a person said to another: ‘Give your clothes to a cleaner,’ and the latter said: ‘I am afraid that He will damage them.’ Then the former responded: ‘Give your clothes to a cleaner and I guarantee them if they are damaged’ without specifying the cleaner, the guarantee is valid. So if He gave them to a cleaner and they were damaged, the guarantor would be responsible even if the person guaranteed for was not named. Similarly, if He said: ‘so and so is a good cleaner, and I guarantee Him against any damage for any person who gives to Him his clothes,’ the guarantee is valid though the guaranteed person is unknown.
