Yahya related to me from Malik from Ibn Shihab from Said ibn al- Musayyab and from Abu Salama ibn Abd ar-Rahman ibn Awf that the Messenger of Allah, may Allah bless him and grant him peace, decreed for partners the right of preemption in property which had not been divided up. When boundaries had been fixed between them, then there was no right of pre-emption.
