Muwatta Malik, Book 31, Hadith 72 (USC-MSA) ⓘ
Yahya related to me from Malik that he had heard that the Messenger of Allah, may Allah bless him and grant him peace, forbade two sales in one sale.
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ . أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ بَيْعَتَيْنِ فِي بَيْعَةٍ .
