The Salat was made compulsory on all the holy messengers of Allah right from the Holy Prophet Hadrath Adam (A.) to till date. However the number & mode was different. & now in Islamic shariat the procedure prescribed is most perfect.
The Night of Decree (Qadr). I will hopefully be able to do this this Ramadan. But then again, only the MOST devoted Muslims can receive the benefit of Lailatul Qadr, one of the last 10 odd nights of Ramadan.
