Narrated by:'Abdul-Malik bin At-Tufail Al-Jazari said
It was narrated that 'Abdul-Malik bin At-Tufail Al-Jazari said:"Umar bin 'Abdul-Aziz wrote to us, saying: 'Do not drink the thickened juice of grapes (obtained by boiling it down) until two-third of it has gone and one-third is left. And every intoxicant is unlawful.'"
أَخْبَرَنَا سُوَيْدٌ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ، عَنْ عَبْدِ الْمَلِكِ بْنِ الطُّفَيْلِ الْجَزَرِيِّ، قَالَ كَتَبَ إِلَيْنَا عُمَرُ بْنُ عَبْدِ الْعَزِيزِ لاَ تَشْرَبُوا مِنَ الطِّلاَءِ حَتَّى يَذْهَبَ ثُلُثَاهُ وَيَبْقَى ثُلُثُهُ وَكُلُّ مُسْكِرٍ حَرَامٌ .
