Hadith 15:348
Abu Bakr narrated to us, he said: Ibn Idris narrated to us, from Layth, from Qays, from Makhul, who said: The Messenger of Allah (may Allah bless him and grant him peace) advised some of my family: "Do not drink wine, for indeed drinking it is the key to every evil."
حدثنا أبو بكر قال حدثنا بن إدريس عن ليث عن قيس عن مكحول قال أوصى رسول الله صلى الله عليه وسلم بعض اهلي ألا يشرب الخمر فإن شربها مفتاح كل شر
