Zayd bin Aslam (may Allah have mercy on him) said about the words of Allah, the Blessed and Exalted, "That is more likely that you will not ta'ulu" [Surah al-Nisa': 3]: That is more likely that those in your care will not become many. And the hadith about the occasion of revelation of this verse has already passed in the Book of Marriage.
