This Question was a give away.
Yes the correct answer is Salat Al-Witr
It is the odd number of Rakats (1,3,5,7,9) performed any time after Salatul-Isha till Salatul-Fajr. This prayer is often mistakenly thought of as part of the Isha prayer but it is not so.
Abu Hurayrah, may Allah be pleased with him, said: “My Khaleel (friend) (i.e. the Prophet (Sallallahu Alayhi wa Sallam) advised me to observe three things and I shall not leave them till I die: 1. “To observe fasting three days every (lunar) month; 2.” To perform the Ad-Duha prayer; 3. To offer Witr prayer before sleeping.” (Reported by Al-Bukhari and Muslim)
