The texts
١٤٣ - مَسْأَلَةٌ: وَالْقَيْءُ مِنْ كُلِّ مُسْلِمٍ أَوْ كَافِرٍ حَرَامٌ يَجِبُ اجْتِنَابُهُ، لِقَوْلِ رَسُولِ اللَّهِ - صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -: «الْعَائِدُ فِي هِبَتِهِ كَالْعَائِدِ فِي قَيْئِهِ» وَإِنَّمَا قَالَ - عَلَيْهِ السَّلَامُ - ذَلِكَ عَلَى مَنْعِ الْعَوْدَةِ فِي الْهِبَةِ. [مَسْأَلَةٌ حُكْمُ طَهَارَةِ الْخَمْرِ وَالْمَيْسِرِ وَالْأَنْصَابِ وَالْأَزْلَامِ]
