if you say: I sell to you for cash at such and such [price], and on credit for such and such [price], and the buyer takes it, he has the choice between the two sales, unless a sale has been concluded on one of them. If the sale occurs like this, it is disliked, it is two sales in one sale, it is rejected, and it is prohibited. If you find your goods intact, you take them; if they have been consumed, you are entitled to the lower of the two prices and the longer of the two terms. ʿAbd al-Razzāq recorded it (14632) from him. 4 - al-Awzāʿī, similarly but in a shortened form, and in it: "It was said to him: What if he takes the commodity on those two conditions? He said: It is at the lower of the two prices to the longer of the two terms." Al-Khaṭṭābī mentioned it in "Maʿālim al-Sunan" (5/99). Then the imams of ḥadīth and language followed their tradition, among them: 5 - Imām al-Nasāʾī, who said under the chapter "Two Sales in One Sale": "It is that he says: I sell you this commodity for one hundred dirhams in cash, and for two hundred dirhams on credit." And similarly, he explained the ḥadīth of Ibn ʿAmr: "Two conditions in a sale are not permissible," which is recorded in "al-Irwāʾ" (1305) and see "Ṣaḥīḥ al-Jāmiʿ" (7520). 6 - Ibn Ḥibbān, said in "Ṣaḥīḥ" (7/225 - al-Iḥsān): "Mention of the prohibition of selling something for one hundred dinars on credit, and for ninety dinars in cash." He mentioned that under the ḥadīth of Abū Hurayrah with the second shortened wording. 7 - Ibn al-Athīr in "Gharīb al-Ḥadīth," as he mentioned that in the explanation of the two previously mentioned ḥadīths. The ruling on installment sales: Other interpretations of (the two sales) have been mentioned, and some of them may come, but what has been mentioned is more correct
