Salam.
I just Failed to understand the example of dog in the verse 7:176
7:176 And if We had willed, we could have elevated him thereby, but he adhered (instead) to the earth and followed his own desire. So his example is like that of the dog: if you chase him, he pants, or if you leave him, he (still) pants. That is the example of the people who denied Our signs. So relate the stories that perhaps they will give thought.
Since dogs cannot sweat, it's their way of cooling their body temperature. Isn't it? Also, some dogs just do it to feel the air brushing against their tongues. So what is the similarity between dog and those people who follow their own desire.
I look forward to hear your thoughts on this.
