The ruling on specifying the end of the year as the term in a forward sale (salam)

Question : Regarding terms referred to as the end of the year, but they do not intend [a specific date].

Answer : Yes, if they do not specify the festival and say "at the end of the year," there is no harm. This is because even the festivals of the disbelievers differ with respect to the end of the year; some occur four or five days before the end of the year, and some are delayed. The important point is that if it is not restricted to the festival, there is no harm.
