بَابُ شُرُوطِ الصَّلَاةِ الَّتِي تَتَقَدَّمُهَا
Translation: Chapter of the conditions of prayer that precede it.
Shurut is the plural of shart, a condition. Such requirements cannot be replaced merely by completing the visible movements of prayer.
Conditions of validity are distinct from the obligations and integrals performed during prayer.
