مُحْكَمٌ

[pass. particle n. of أَحْكَمَهُ;] applied to a building [&c.,] Made, or rendered, firm, stable, strong, solid, compact, &c.; held to be secure from falling to pieces. (KT.)

And hence, A passage, or portion, of the Qur'an of which the meaning is secured (أُحْكِمَ) from change, and alteration, and peculiarization, and interpretation not according to the obvious import, and abrogation. (KT.) And سُورَةٌ مُحْكَمَةٌ A chapter of the Qur'an not abrogated. (K.) And الايَاتُ المُحْكَمَاتُ, [see Qur'an, 3:5, where it is opposed to ايَاتٌ مُتَشَابِهَاتٌ,] The portion commencing with قُلْ تَعَالَوْا أَتْلُ مَا حَرَّمَ رَبُّكُمْ [Qur'an, 6:152, to the end of the chapter: or the verses that are rendered free from defect or imperfection, so that the hearer thereof does not need to interpret them otherwise than according to their obvious import; such as the stories of the prophets; (K;) or so that they are preserved from being susceptible of several meanings. (Bd in iii. 5.) And المُحْكَمُ The portion of the Qur'an called المُفَصَّلُ [q. v.]; because nought thereof has been abrogated: or, as some say, what is unequivocal, or unambiguous; because its perspicuity is made free from defect, or imperfection, and it requires nothing else [to explain it].
