Machine translationRead the Arabic original
Question : Ibn 'Umar, regarding the benefits, what does it mean?
Answer : Yes. Abu 'Abdullah. No, that is his opinion; this is his opinion, not a hadith that requires opposing the community. He holds that they are the worst of creation, because their danger is greater than the danger of the Jews and the Christians, because they display righteousness. In fact, if you are around them at night, you hear the sound of their recitation of the Qur'an, their weeping, and they have much fasting, prayer, and charity.
