ق ط م رq-ṭ-m-r
quadriliteral — قِطْمِيْرqiṭmīr: the thin membrane wrapped around a date-stone; among the Arabs it was the proverbial example of an utterly insignificant and worthless thing. Two other words of the same family occur in the Quran: نَقِيْرnaqīr (the pit of the date-stone) and فَتِيْلfatīl (the thread of the date-stone) — all three for the smallest of quantities. Only once in the Quran: ﴿وَالَّذِيْنَ تَدْعُوْنَ مِنْ دُوْنِهِۦ مَا يَمْلِكُوْنَ مِنْ قِطْمِيْرٍ﴾ (Fāṭir 35:13).
