The Messenger of Allah ﷺ said, "Three things contain blessing: a sale on credit, a partnership of profit-sharing, and mixing wheat with barley for the household, not for sale."
حدثنا الحسن بن علي الخلال حدثنا بشر بن ثابت البزار حدثنا نصر بن القاسم عن عبد الرحمن بن داود
قال رسول الله ﷺ ثلاث فيهن البركة البيع إلى أجل والمقارضة وأخلاط البر بالشعير للبيت لا للبيع

Its chain is very daif. Aqeeli reported it in 3/80 from the hadith of Nasr bin Qasim, narrating it in this manner, and he said about Abdul-Raheem, "Unknown in transmission, his hadith is not preserved." Nasr is unknown (Taqrib 522), and Salih is of unknown status (Taqrib 230). The hadith was declared daif by Busiri and by Hafiz in Bulugh Maram. Ibn Jawzi mentioned it in Al-Mawduat 22/248, 249, and said, "Fabricated." Bukhari said about Nasr, "His hadith is fabricated." And Dhahabi said, "The chain is obscure and the text is false."
