وَأَعْلَمُ مَا فِي الْيَوْمِ وَالْأَمْسِ قَبْلَهُ ۞ وَلَكِنَّنِي عَنْ عِلْمِ مَا فِي غَدٍ عَمِ
I know what belongs to today and yesterday before it, but I am blind to knowledge of what tomorrow holds.
Al-ams is yesterday; ghad is tomorrow. ʿAmi literally describes blindness but here figuratively means ignorance of future events. Zuhayr distinguishes learning from what is present or past from claiming complete knowledge of what has not yet happened.
