When the Prophet Muhammad, upon him be peace, would come to salat, he would ecstatically overflow with extra rakats, sometimes before, sometimes after the set pattern of fard rakats. Once lovers establish the basic five-times daily salat, they naturally overflow into this state of gratitude, offering additional rakats.
Fajr: 2 sunna rakats preceding the 2 fard rakats
Zuhr: 4 sunna preceding the 4 fard, and 2 sunna following the fard
Asr: 4 sunna preceding the 4 fard. After this fard, no prostrations are made until just after sundown.
Maghrib: 2 sunna after the fard
Isha: 4 sunna before the 4 fard, 2 sunna after the fard. After the 2 sunna, many crown the prayers of the day with 3 more rakats. These 3 rakats are called the witr prayer. The witr prayer has a unique design: after the Fatiha and other ayat(s) of Quran is chanted in the third rakat, raise the hands intoning Allahu Akbar. Remain standing and quietly offer a personal supplication or another Fatiha. Then, with another Allahu Akbar, move to the bowing posture, and continue to follow the pattern of a three-rakat prayer.
