The ruling on taking a guarantor and a pledge in a forward sale and the sale of goods when in need

The questioner:
Peace.

The Shaykh:
But according to the Hanafis, it is permissible. Welcome, welcome, welcome.

The questioner:
It is acceptable to take a guarantee or something else.

The Shaykh:
No, it is not valid to take a guarantor or a pledge for it, because this is a means of diverting it to something else.

The questioner:
The Shaykh (may Allah have mercy on him) found the opinion of his Eminence regarding a person who agrees with another individual to provide him with goods when he needs them or has a need for them, on the condition that he takes an increase over the agreed amount of the forward sale, knowing that the specification is to be as precise as possible.

The Shaykh:
This involves ambiguity. He provides the goods when he needs them; when is the time of his need known? There is ambiguity here, how is that? But if he says, "I will give you money now on the condition that you provide me with the goods at such and such a time," a specific time, then this forward sale is fine. But if he says, "Provide me with the goods when I need them," that is an unknown term, so it is not valid. Yes.
