[Machine] Abdullah ibn Mas'ood said, "O people, a time has come upon us in which we are not the ones passing judgments and we are not there. Indeed, Allah has informed us of what you see. So whoever is presented with a matter after today, let him judge according to what is in the Book of Allah. And if a matter comes to him that is not in the Book of Allah but was decreed by the Messenger of Allah, let him judge according to it. And if a matter comes to him that is not in the Book of Allah and was not decreed by the Messenger of Allah, let him judge according to what the righteous have decreed. And if a matter comes to him that is not in the Book of Allah, was not decreed by the Messenger of Allah, and the righteous have not decreed it, then he should use ijtihaad and not say, 'I fear' or 'I think.' Indeed, the halal (permissible) is clear and the haram (forbidden) is clear, and between them are matters that are doubtful. So leave what makes you doubt for that which does not make you doubt." This narration was reported by Shu'bah from Al-A'mash from Umamah ibn Umair from Huraith ibn Zuhair from Abdullah ibn Mas'ood. Abu Nasr ibn Qatadah informed us, who was informed by Abu Al-Husayn Muhammad ibn Abdullah Al-Quhistani, who informed us, who was informed by Abu Umar, who was informed by Shu'bah, who was informed by Al-A'mash, who mentioned it.
