Qsaibeh, (القصيبة), El Kossaybeh, also known as El Qsaïbé (in Arabic: القصيبة) is a village in southern Lebanon on the northern side of the Litani's river.
In the 1596 tax records, it was named as a village, Qusayba, in the Ottoman nahiya (subdistrict) of Sagif, part of Safad Sanjak, with a population of 26 households and 7 bachelors, all Muslim. The villagers paid a fixed tax-rate of 25 % on agricultural products, such as wheat, barley, olive trees, cotton, goats and beehives, in addition to "occasional revenues"; a total of 4,300 akçe.[1] [2]
In 1875, Victor Guérin found here a village with 300 inhabitants, mostly Metualis and some Greek Orthodox. The mosque was possibly a former church.[3]
