Human faculties: hearing, sight, and intellect (heart)

ثُمَّ سَوَّىٰهُ وَنَفَخَ فِيهِ مِن رُّوحِهِۦ ۖ وَجَعَلَ لَكُمُ ٱلسَّمْعَ وَٱلْأَبْصَـٰرَ وَٱلْأَفْـِٔدَةَ ۚ قَلِيلًا مَّا تَشْكُرُونَ

Then He proportioned him and breathed into him from His [created] soul and made for you hearing and vision and hearts [i.e., intellect]; little are you grateful.
