Translation of the verse 9 from Surah Al-Mu’minun : Number of verses 118 - - page 342 - Part 18.
And those who strictly guard their (five compulsory congregational) Salawat (prayers) (at their fixed stated hours).
And they who carefully maintain their prayers -
(23:9) and who strictly guard their Prayers. *9
*9) Salawat is plural of Salat. In verse 2 the act of Salat itself was implied, but here the plural number implies the individual Prayers offered in their own times. "They strictly guard their Prayers": they strictly adhere to the prescribed times of the Prayers: they perform them with due regard for their pre-requisites, conditions and articles with clean body and dress and necessary ablutions: they do not regard their Prayers as an unnecessary burden, which has to be cast off somehow: they do not recite mechanically but understand what they recite and are conscious that they are supplicating their Lord like humble servants.
