5. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhammad ibn ‘Isma’il from Mansur ibn Yunus from Muhammad al-Halabiy who has said the following: “I once was sitting with the judge and abu Ja’far , was also there, when two men came to him and one of them said, ‘I rented a camel from this man to carry my goods to the mine and I stipulated with him to come to me to the mine on so and so day because that was the market day and I was afraid of missing it. If you will be held up I will reduce the rent for each day that you are held up so and so much amount. He kept me on hold for so and so many days.’ The judge said, ’This is an invalid stipulation. You must pay his rent.’ When the man stood up he came to abu Ja’far , who said, ’His stipulation is permissible as long as he does not drop all of the rent.’”
