[Machine] I came to the Messenger of Allah (PBUH) and said, "O Messenger of Allah, I shoot with my bow and sometimes I hit an animal and sometimes I miss. What is permissible for me to eat and what is forbidden?" We are in the land of the People of the Book and they eat pork in their dishes and drink wine in them. So can we eat and drink from them?" He said, "As long as you recite the name of Allah and your arrow reached its target, then eat. But if you find dishes of the People of the Book empty, do not eat from them. And if you do not find them empty, then wash them with water thoroughly and then eat from them. And in this, there is evidence that the requirement for washing is only when knowledge of its impurity is known. And Allah knows best."
أَتَيْتُ رَسُولَ اللهِ ﷺ فَقُلْتُ أَيْ رَسُولَ اللهِ إِنِّي أَرْمِي بِقَوْسِي فَمِنْهُ مَا أُدْرِكُ ذَكَاتَهُ وَمِنْهُ مَا لَا أُدْرِكُ فَمَاذَا يَحِلُّ لِي وَمَا يَحْرُمُ عَلَيَّ؟ إِنَّا فِي أَرْضِ أَهْلِ الْكِتَابِ وَهُمْ يَأْكُلُونَ فِي آنِيَتِهِمُ الْخِنْزِيرَ وَيَشْرَبُونَ فِيهَا الْخَمْرَ فَنَأْكُلُ فِيهَا وَنَشْرَبُ؟ قَالَ كُلْ مَا رَدَّ عَلَيْكَ قَوْسُكَ وَذَكَرْتَ اسْمَ اللهِ فَكُلْ وَإِنْ وَجَدْتَ عَنْ آنِيَةِ أَهْلِ الْكِتَابِ غِنًى فَلَا تَأْكُلْ وَإِنْ لَمْ تَجِدْ عَنْهَا غِنًى فَارْحَضُوهَا بِالْمَاءِ رَحْضًا شَدِيدًا ثُمَّ كُلُوا فِيهَا وَفِي هَذَا دَلَالَةٌ عَلَى أَنَّ الْأَمْرَ بِالْغَسْلِ إِنَّمَا وَقَعَ عِنْدَ الْعِلْمِ بِنَجَاسَتِهَا وَاللهُ أَعْلَمُ
