The noun naʾil is not in the Quran, but its verb is, about sacrifice: “Neither their flesh nor their blood reaches (yanala) Allah, but what reaches Him from you is piety” (22:37); “You will never attain righteousness until you spend from what you love” (3:92).
Meaning of the name Nael
Naʾil is the active participle of nala, “to obtain, to attain” (root n-y-l; the neighbouring root n-w-l gives nawal, “gift”): one who achieves what he seeks, and one who gives. The name, very popular in France (Naël), the Levant and the Gulf, has Naʾila as its feminine. In Turkish, nail means “having obtained” (nail olmak, “to obtain”).
Their meat will not reach Allāh, nor will their blood, but what reaches Him is piety from you. Thus have We subjected them to you that you may glorify Allāh for that [to] which He has guided you; and give good tidings to the doers of good.
Never will you attain the good [reward] until you spend [in the way of Allāh] from that which you love. And whatever you spend - indeed, Allāh is Knowing of it.
And [mention, O Muḥammad], when Abraham was tried by his Lord with words [i.e., commands] and he fulfilled them. [Allāh] said, "Indeed, I will make you a leader for the people." [Abraham] said, "And of my descendants?" [Allāh] said, "My covenant does not include the wrongdoers."
