Wallatheena hum AAala salawatihim yuhafithoon (surah Muminun: 9)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(23:9) and who strictly guard their Prayers. *9

Wallazeena hum `alaa Salawaatihim yuhaafizoon

*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.
