Sayyidina Ibn Abbas reported that someone asked him to explain the verse: He explained: They were the people who embraced Islam in Makkah and longed to join the Prophet (SAW), but their wives and children prevented them from doing so. Thus, when they came to Madinah, they found that others had gained tremendous understanding of religion, so they resolved to punish them (that is, their wives and children). It was then that this verse was revealed: "O you who believe, surely among your wives and your children, there are (some) enemies to you, so be aware of them." (64: 14)
