In Arabic, there are several words for prayer. The word “salát”, which appears here   [Paragraph 6 of the Kitab-i-Aqdas] in the original, refers to a particular category of prayers, the recitation of which at specific times of the day is enjoined on the believers. To differentiate this category of prayers from other kinds, the word has been translated as “obligatory prayer”.

Bahá’u’lláh states that “obligatory prayer and fasting occupy an exalted station in the sight of God” (Q and A 93). ‘Abdu’l-Bahá affirms that such prayers are “conducive to humility and submissiveness, to setting one’s face towards God and expressing devotion to Him”, and that through these prayers “man holdeth communion with God, seeketh to draw near unto Him, converseth with the true Beloved of his heart, and attaineth spiritual stations”.
