Chapter on Conditions and Options in Sales

Imam عليه السلام said: "Whenever a man buys something from another man, they both have the option (to cancel the deal) until they part ways. Once they part, the sale becomes binding."

Imam عليه السلام was asked about a man who purchased a slave or an animal from another man and stipulated a condition for one or two days. If the slave dies, the animal perishes, or a defect occurs during that period, who is responsible for the loss? Imam عليه السلام said: "There is no liability on the buyer until the condition period ends and the sale becomes final."

Ishaq ibn Ammar narrated from the Righteous Servant of Allah سبحانه وتعالى (Imam Musa ibn Jafar Al-Kadhim عليه السلام) who said: "Whoever buys an item, and three days pass without him coming (to confirm or claim it), then the sale is void."

Abdullah ibn Sinan narrated from Abu Abdillah عليه السلام who said: "Muslims are bound by their conditions, except for any condition that contradicts the Book of Allah سبحانه وتعالى, the Mighty and Exalted, which is not permissible."

Jamil narrated from Zurarah, from Abu Ja'far Imam Muhammad ibn Ali Al-Baqir عليه السلام, who said: I asked him about a man who buys merchandise from another man and then leaves it with him, saying, "I will bring you its price." Imam عليه السلام said: "If he brings the payment within three days, then the sale is valid; otherwise, there is no sale for him."

In another narration, Ibn Faddal narrated from Al-Hasan ibn Ali ibn Ribbat, from someone who narrated it from Abu Abdillah عليه السلام, who said: "If an animal develops a defect within three days, it is the responsibility of the seller."
