Praise be to Allaah.
If that was due to ignorance on your part, then you do not
have to do anything. If you were not sure whether it was saffron or not,
then you do not have to do anything. If you were certain that it was saffron
and you knew that it is not permissible for the muhrim to drink coffee in
which there is saffron, then if there was a fragrance, then he did something
wrong, but if there was nothing but the colour, then there is no sin on him
Shaykh Muhammad ibn ‘Uthaymeen (may Allaah have mercy on
Shaykh ‘Abd al-‘Azeez ibn Baaz (may Allaah have mercy on him)
was asked: A woman who was in ihraam for ‘Umrah drank coffee with saffron
before completing ‘Umrah. Is saffron a type of perfume? Did it spoil the
‘Umrah or not?
The muhrim who drinks coffee containing saffron is doing
wrong, because saffron is a kind of perfume and should not be used in coffee
by the muhrim, just as he should not use it on his clothes or body when he
is in ihraam. If the man or woman in ihraam does that out of ignorance or by
mistake, then they do not have to do anything, but if they do that
deliberately, knowing that he is in ihraam, then it is not permissible. He
(the muhrim) should give charity, feeding six poor persons, giving each one
half a saa’ of dates or wheat, or fast for three days, or sacrifice a sheep.
