Re: Fatima (RA)'s wedding du'a
Wa iyyakum. :)
Re other du'as -
my brother (who found the translation) is also getting married, it'll be a double wedding (walima/shaadi) insha'allah, and on his wedding invitation he's chosen the following verse from Surah al-Furqan:
"Our Lord! Grant us wives and offspring who will be the comfort of our eyes, and give us (the grace) to lead the righteous." (Ameen)
(25:74)
I like that one as well. =)
