Sa'id bin Jubayr (may Allah have mercy on him) said regarding the words of Allah Almighty, "And there is no sin upon you in what you hint of a proposal of marriage to women" [Surah al-Baqarah: 235]: It is that a man says (to a woman) during her waiting period: "I intend to marry, and if I marry, I will treat my wife well."
