﴿ ضَرَبَ لَكُم مَّثَلًۭا مِّنْ أَنفُسِكُمْ ۖ هَل لَّكُم مِّن مَّا مَلَكَتْ أَيْمَٰنُكُم مِّن شُرَكَآءَ فِى مَا رَزَقْنَٰكُمْ فَأَنتُمْ فِيهِ سَوَآءٌۭ تَخَافُونَهُمْ كَخِيفَتِكُمْ أَنفُسَكُمْ ۚ كَذَٰلِكَ نُفَصِّلُ ٱلْءَايَٰتِ لِقَوْمٍۢ يَعْقِلُونَ ﴾

“He propounds unto you a parable drawn from your own life: Would you [agree to] have some of those whom your right hands possess as [full-fledged] partners in whatever We may have bestowed upon you as sustenance, so that you [and they] would have equal shares in it, and you would fear [to make use of it without consulting] them, just as you might fear [the more powerful of] your equals? Thus clearly do We spell out these messages unto people who use their reason.”

لَهُ الْمَثَلُ الْأَعْلَىٰ (For Him is the highest attribute - 30:27) The word مَثَل mathal is used for any such thing which has resemblance and similarity with something else, but its being exactly like that is not necessary. Therefore, the Qur'an has used the word 'mathal' for Allah Ta’ ala at several places, as in this very verse, and in another but Allah Ta’ ala's Being is completely beyond resemblance. (That is why the word 'mathal' has been translated above as 'attribute', which is also a possible lexical meaning of the word.)
