Umar bin Al-Khattab wrote to some of his workers saying: 'Give to the Muslims thickened grape juice when two thirds of it have gone and one-third is left.'

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.

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.'

Ali, may Allah be pleased with him, used to give the people thickened grape juice into which flies would fall and not be able to get out again.

I asked Sa'eed: 'What is the drink that 'Umar bin Al-Khattab, may Allah be pleased with him, regarded as permissible?' He said: 'That which has been cooked until two-third has gone and one-third is left.'

Abu Ad-Darda' used to drink that of which two-third had gone and one-third was left.

He used to drink thickened grape juice that of which two-third had gone and one-third was left.

I heard Sa'eed bin Al-Musayyab say, when a Bedouin asked him about a drink that had been cooked and reduced by half: 'No, not until two-third has gone and one-third is left.'

When At-Tila' (thickened grape juice) has been cooked and reduced to one-third, then there is nothing wrong with it.
