ا ب لʾ-b-l
— إِبِلibil (collective noun (ism jamʿ); no singular is formed from its letters): camels; among the Arabs these were the greatest blessing and the measure of wealth, which is why the Quran presents them as a proof: ﴿أَفَلَا يَنْظُرُوْنَ إِلَي الْإِبِلِ كَيْفَ خُلِقَتْ﴾ (Al-Ghāshiyah 88:17)
أَبَابِيْلabābīl: flocks upon flocks, groups coming one after another; the well-known view of the lexicographers is that it has no singular from its own letters (like عَبَادِيْدʿabādīd and شَمَاطِيْطshamāṭīṭ), while some have given إِبَّالَةibbālah or إِبِّيْلibbīl as its singular. ﴿وَأَرْسَلَ عَلَيْهِمْ طَيْرًا أَبَابِيْلَ﴾ (Al-Fīl 105:3). This root occurs three times in the Quran, and only as a noun.
