Almuntakhab Fi Tafsir Alquran Alkarim

Lightning very nearly snatches their sense of sight; as often as it emits for them gleams they proceed under its light and when it darkens, their eyes shrivel into darkness in their heads and they stand dead; and had Allah willed He would have deprived them of their sense of hearing and that of sight, faculties divine; He is indeed Qadirun (Omnipotent) to effect all things

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(2:20) The lightning terrifies them as if it were going to snatch away their eyesight from them. When they see light, they move on a little further and When it becomes dark for them, they stand still *19 . Had Allah so willed, He could have deprived them totally of their hearing *20 and their sight. Most surely Allah has power over everything.

*19). The first parable refers to those hypocrites who disbelieved completely but had become Muslims merely, to further their worldly interests. The second parable refers to those who were prone to doubt and hesitation or whose faith was weak; who believed in the Truth but not to the extent of exposing themselves to hardships for its sake. The 'violent rainstorm' here alludes to Islam, which came to the world as a blessing. 'Pitch-dark clouds, thunder and lightning' refer to trials, tribulations and difficulties which confronted the Islamic movement, owing to the violent opposition and resistance of those committed to Ignorance. The last part of the parable portrays the state of mind of the hypocrites. They move a little ahead when circumstances seem favorable, but when either difficulties cloud the horizon, or when they are given directives which run counter to their desires or inherited prejudices, they are seized with alarm and come to a halt.
*20). Just as God has completely deprived the first category of hypocrites of their 'light of perception', He could have rendered these other hypocrites totally blind and deaf. But it is not God's way to deprive anyone of sight and hearing while he is willing to see and hear. Hence, God allowed them to retain their sight and hearing to the extent they were prepared to see and hear the Truth.

چمک سے ان کی حالت یہ ہو رہی ہے کہ گویا عنقریب بجلی اِن کی بصارت اُچک لے جائے گی جب ذرا کچھ روشنی انہیں محسوس ہوتی ہے تو اِس میں کچھ دور چل لیتے ہیں اور جب ان پر اندھیرا چھا جاتا ہے تو کھڑ ے ہو جاتے ہیں اللہ چاہتا تو ان کی سماعت اور بصارت بالکل ہی سَلب کر لیتا، یقیناً وہ ہر چیز پر قادر ہے
