"Umar bin Al-Khattab, may Allah be pleased with him, wrote to us (saying): 'Cook your drinks until the share of the Shaitan is gone, for he has two (shares) and you have one.'"
Sunan an-Nasa'i Book 51, Hadith 179
← Previous Hadith "I saw the letter of 'Umar bin Al-Khattab to Abu Musa (in which he said): 'A caravan came to me from Ash-Sham carrying a thick black paint like the pitch that is daubed on camels. I asked them how long they cooked it, and they told me that they cooked it until it was reduced by two-third. So the bad two-third had gone, one-third to take away evil and one-third to take away the bad smell. So let those who are with you drink it."
