It is no offence if you make indirect proposal of marriage to widows during their waiting term or keep it concealed in your hearts: for Allah knows that you will naturally think of them. But be careful not to make any secret engagement. If you have to do anything, do it in an honourable way. And you should not settle anything finally about the marriage until the waiting term expires. Understand it well that Allah even knows what is hidden in your hearts; so fear Him. Also know that Allah is Lenient and Forgiving.
