And أَرَّخَ البَيِّنَةَ He dated, or mentioned the date of, the evidence, proof, or voucher: in the contr. case saying, أَطْلَقَ. (Msb.) Some say that تأريخ is an arabicized word, (L, Msb,) borrowed by the Muslims from the people of the Bible: [i. e., from the Jews or Christians; apparently from the Hebr. יָרֵחַ the “moon,” or יֶרַח “a month;“ or from the Chald. יְרַח “a month;” as observed by Golius:] (L:) others say that it is [pure] Arabic: (Msb, TA:) some, that it is formed by transposition from تَأْخِيرٌ.
