 Well, first of all, it's not at all clear that Mohammed Daif was killed. Hamas is denying it. The Israelis have not actually tried to claim it. What they have claimed is that his deputy, Rafa Salameh, who was the commander of Hamas's Khan Yunus Brigade and was the deputy to Daif, was killed. The fact that they're not saying that Mohammed Daif was killed is probably an indication that he was not.
