There are shops at Souq Waqif that have them. There is also a shop on Shahrah Umm AlDhoom just opposite Saudi Hypermarket in Muaither that also stocks them. However, you may need to have the bottle packed and sealed in polyethylene to allow for the airline people to accept them at the time of checking in at the airport. Possibly, the people at Souq Waqif may be able to guide you where the packing could be done. However, you may not be required to do the special packing if you intend to hand-carry the bottle. Check with your airline on the rules.
