Surah 80. Abasa, Ayah 9

The fear in the blind man's heart may have been two-fold. (1) He was humble and God-fearing, not arrogant and self-sufficient; (2) being poor and blind, he feared to intrude; yet his earnest desire to learn the Qur-an made him bold, and he came, perhaps unseasonably, but was yet worthy of encouragement, because of the purity of his heart.
