Prayer consists of twelve obligatory acts. Six of them are called conditions of prayer (shurut al-salat) because they are required to be fulfilled before beginning to perform the prayer, which are:
1) Taharah min al-Hadath (Purification from spiritual impurities),
2) Taharah min al-Najasah (Purification from material impurities)
3) Satr al-Awrah (Rules of Modesty),
4) Istiqbal al-Qiblah (Turning towards the direction of Mecca)
5) The Timing for the Prayer
6) Intention
The other six obligatory acts are called essential parts of the ritual prayer (rukn al-salat). These requirements must be fulfilled while performing the prayer. These are:
1) Takbir al-Iftitah (Opening Takbir)
2) Qiyam (Standing)
3) Qira'ah (Recitation of the Qur'an)
4) Ruku (Bowing Down)
5) Sajdah (Prostration)
6) Qadah al-Akhirah (The Final Sitting)
