How long to wait after sunrise before offering fajr prayer?

Assalamu'Alaikum Fellow Community members, This is my very first question to the community and it's a simple one. Is there a hadith or quranic verse which tells how long one has to wait after sunrise before offering the Fajr prayer? Obviously this is when one has missed the fajr time and woken up right after sunrise time has past. Answers with authentic references will be much appreciated.
