مِرْفَقٌ
2.
Also A thing by which one profits, or gains advantage or benefit. (S, O, Msb, K.) It is said in the Qur'an, 18:15, وَيُهَيِّيءُ لَكُمْ مِنْ أَمْرِكُمْ مِرْفَقًا or
مَرْفِقًا, according to different readers, [i. e. And He will prepare for you a condition of your case by which ye shall profit], but no one reads
مَرْفَقًا, (S, O,) which, however, is allowable, meaning
رِفْقًا. (S. [See رِفْقٌ, last sentence.]) The plural is مَرَافِقُ. (Msb.)
3.
[Hence,] مَرَافِقُ الدَّارِ
Such appertenances [or conveniences] of the house as the privy and the kitchen and the like: (Mgh, Msb:) or the sinks, and the like, of the house: (S, O, K:) and particularly privies: (O:) when used in these senses, the singular is مِرْفَقٌ only, with kesr to the م and fet-h to the ف, (Mgh, Msb,) likened to the noun signifying an instrument. (Msb.) [See also حَيِّزٌ, in article حوز.]
4.
And from the same words in the sense explained in the second sentence above, (Msb,) مِرْفَقٌ and
مَرْفِقٌ signify also The elbow, or elbow-joint; the place where the
ذِرَاع
joins upon the
عَضُد; (S, O, K;) [in other words,] the place where the
عَضُد
is connected with the
سَاعِد; (Mgh;) the مرفق
of a man: (Msb:) [and in like manner in a beast, the elbow, or elbowjoint, as in the JK, S, O, and K, voce أَرْفَقُ; and in countless other instances: but in the K voce رُكْبَةٌ (q. v.), it seems to be applied to the knee of a beast:] plural as above. (Msb.)
