I play The Generous Widow while my opponent has both Nicanor in play and Rain Becomes Dust active.  Which instead happens first, Nicanor or Rain Becomes Dust?

We had these two cards duking it out the other day in my playgroup. I was controlling Nicanor in a multi-player game. I made a successful rescue against a player with RBD active, and he surrendered the Rejoice LS to me. Normally, under RBD, I wouldn't have my draw "insteaded" because I do not control the ability causing me to draw. My Nicanor insteads the Rejoice LS's, so instead of all players draw 1, all players draw 1   

...HOWEVER I then controlled the draw ability, and got hit with RBD...
