رِطْلٌ

and رَطْلٌ, (S, Mgh, O, Msb, K,) the former of which is the better known, (Msb, TA,) or the more chaste, (O, TA,) [but the latter is that which is now in common use,] A certain thing with which one weighs, (Mgh, O, Msb,) or which one uses as a measure of capacity: (Mgh, Msb:) [or rather both: a pound-weight: and a pint-measure: and also a pound of anything: and a pint of anything:] the half of what is termed مَنًا: (S:) according to the standard of Baghdád, twelve ounces; the ounce (أُوقِيَّة) being an إِسْتَار and two thirds of an استار; and the استار being four مَثَاقِيل and half of a مِثْقَال; and the مثقال being a دِرْهَم and three sevenths of a درهم; and the درهم being six دَوَانِق; and the دَانِق being eight حَبَّات and two fifths of a حَبَّة; so that the رطل is ninety مثاقيل; i. e. a hundred and twenty-eight دَرَاهِم and four sevenths of a درهم (Msb:) or, according to A 'Obeyd, a hundred and twenty-eight دراهم of the weight of seven (وَزْنَ سَبْعَةٍ [explained voce دِرْهَمٌ]): (Mgh:) or twelve ounces; the ounce (أُوقِيَّة, i. e. the ounce of the Arabs, TA,) being forty دراهم; (Mgh, K, TA;) so that the whole is four hundred and eighty دراهم: (Mgh, TA:) this is the Syrian رطل: (TA:) and thus it is, according to El-Harbee, in the saying, السُّنَّةُ فِى النِّكَاحِ رِطْلٌ [meaning The usage of the Prophet in the case of marriage was to give a رطل of silver]: (Mgh, TA:) so says Az in the T: (Mgh:) or, as is [also] said by Az, it is in this instance twelve ounces and a نَشّ; the نشّ being twenty [دراهم] so that the whole is five hundred دراهم; as is related on the authority of 'Áïsheh: but in a tradition 'Omar, twelve ounces, without the mention of the نشّ: according to the lawyers, [however,] when the رطل is mentioned without restriction, what is meant thereby is the رطل of Baghdád: (TA:) [as a measure of capacity, i. e. a pint,] it is said in the A [&c.] to be the eighth part of the صَاع; the half of the مُدّ; (TA;) [i. e.] the half of the مَنّ: and hence applied to one of the vessels of the vintner [apparently because it contains a pint]: (Har p. 650:) plural أَرْطَالٌ.
