RABBU ʾN-NAUʿ (رب النوع‎). The “Lord of the Species.” An angel who is said to preside over the animate and inanimate creation, viz.: nabātāt, “vegetable”; ḥaiwānāt, “animal”; jamādāt, “inanimate” (stones, earth, &c.), called al-ʿālamu ʾs-suflī, “the lower creation,” as distinguished from al-ʿālamu ʾl-ʿulwī, “the heavenly world.” (See G͟hiyās̤u ʾl-Lug͟hah.)

RABĪʿU ʾL-ĀK͟HIR (ربيع الاخر‎). “The last spring month.” The fourth month of the Muḥammadan year. [[MONTHS].]

RABĪʿU ʾL-AWWAL (ربيع الاول‎). “The first spring month.” The third month of the Muḥammadan year. [[MONTHS].]

RACHEL. Arabic Rāḥīl (راحيل‎). Heb. ‏רָחֵל‎, Rahel. The wife of Jacob and the mother of Joseph. Not mentioned in the Qurʾān, but the name occurs in commentaries.

The English form Rachel is a strange error on the part of our translators, who almost invariably represent the Hebrew ‏ח‎ by the letter h. The correct form, Rahel, which is the form familiar to Muslim writers, occurs once in the English Bible, [Jer. xxxi. 15].

AR-RAʿD (الرعد‎). “Thunder.” The title of the XIIIth Sūrah of the Qurʾān, in the 14th verse of which the word occurs. “The thunder celebrates his praise.”
