There is a very good article at http://www.journeytojannah.com/salah.asp
That contains the following information:
The Second Pillar of Islam - SalahSalah is the name given to the formal prayer in Islam. Salah is one of the obligatory rights of the religion, to be performed five times a day by Muslims. The importance of the salah can be understood by the following hadith.
On the authority of Abu 'Abd al-Rahman 'Abdullah bin 'Umar bin al-Khattab, radiyallahu 'anhuma, who said: I heard the Messenger of Allah, sallallahu 'alayhi wasallam, say: "Islam has been built upon five things - on testifying that there is no god save Allah, and that Muhammad is His Messenger; on performing salah; on giving the zakah; on Hajj to the House; and on fasting during Ramadhan."
[Al-Bukhari & Muslim]
Salah is performed five times a day: at dawn (fajr), noon (dhuhr), in the afternoon (asr), at sunset (maghrib) and nightfall (isha'a)
