I heard Umm Salama narrate from the Prophet ﷺ this hadith. She said that they were disputing over inheritances and matters whose evidence had faded. He said, "I judge between you only by my opinion in matters concerning which nothing has been revealed to me."
حدثنا إبراهيم بن موسى الرازي أخبرنا عيسى حدثنا أسامة
سمعت أم سلمة عن النبي ﷺ بهذا الحديث قال يختصمان في مواريث وأشياء قد درست فقال إني إنما أقضي بينكم برأيي فيما لم ينزل علي فيه
