Selling an Item of Merchandise Which the Seller Does Not Yet Have in His Possession

7. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from al-Nadr ibn Suwayd from ‘Abd Allah ibn Sinan who has said the following: “Abu ‘Abd Allah عليه السلام, has said, ‘It is lawful for a man to sell goods which are not with him in the form of Musawamah (fixed price regardless of capital), then buy for him the goods he demands and make it necessary for yourself thereafter to ask him to sell it to you.’”
