Translation:

45. "O my father! I fear lest a Penalty afflict thee from (Allah) Most Gracious so that thou become to Satan a friend."

Notes (Tafseer)

2497. To entertain a feeling of friendliness, instead of aversion, to Evil, is in itself a degradation of our nature, a Penalty which Allah imposes on our deliberate rejection of the Truth. And the friendliness to Evil also implies the sharing of the outlawry of Evil.
