They will make excuses to you when you have returned to them. Say, "Make no excuse - never will we believe you. Allāh has already informed us of your news [i.e., affair]. And Allāh will observe your deeds, and [so will] His Messenger; then you will be taken back to the Knower of the unseen and the witnessed, and He will inform you of what you used to do."
But among the bedouins are some who believe in Allāh and the Last Day and consider what they spend as means of nearness to Allāh and of [obtaining] invocations of the Messenger. Unquestionably, it is a means of nearness for them. Allāh will admit them to His mercy. Indeed, Allāh is Forgiving and Merciful.
