How does one pray Istikhara if two people propose to me at the same time?

It is permissible to perform a single Istikhara prayer for both suitors, or a separate prayer for each one. When performing Istikhara for both with a single prayer, the well-known supplication is recited with the mention of: "If You know that my marriage to so-and-so is good for me... and if You know that my marriage to so-and-so is evil for me..." And there is no harm in asking Allah to marry her to the better of the two, for if Allah decrees marriage to one of them, then that is what Allah has chosen.
