بَيْنَ الحَايءِطِينَ: in the M, الحَاجِزُ بين الحايءطين, i. e. a partition between two gardens, or walled gardens of palm-trees: the former I regard as the right reading (though SM thinks the contrary); for it expresses a well-known meaning of تِير in Persian; and it is said that تِيرٌ is] a Persian word, arabicized.
