Hazrat Moulana Ashraf Ali Thanwi (rahmatullahi ‘alaih) once mentioned:
People generally pay more attention to and show more concern towards the external actions. While the external actions are extremely essential, the thing of greater significance and importance is purifying the heart. We should look at how much of love and reverence there is in the heart for Allah Ta‘ala and his Rasul (sallallahu ‘alaihi wasallam). There are many people from rural areas and villages who despite being uncultured, possess within their hearts great love and reverence for Allah Ta‘ala and his Rasul (sallallahu ‘alaihi wasallam). The love of Allah Ta’ala and his Rasul (sallallahu ‘alaihi wasallam) has completely penetrated and saturated their hearts. This is what is truly needed – the importance, respect and reverence of Deen to settle in the heart. (Malfoozaat Hakeemul Ummat 7/218)
Note: There are many who claim to have the love of Allah Ta’ala and his Rasul (sallallahu ‘alaihi wasallam) within their hearts, yet the lives they lead totally contradict the commands of the Shari’ah and the Mubaarak Sunnah of Rasulullah (sallallahu ‘alaihi wasallam). The level of love and reverence we have in our hearts for Allah Ta’ala and His Rasul (sallallahu ‘alaihi wasallam) will be determined through the loyalty and obedience we show to the commands of the Shari’ah and the Sunnah of Rasulullah (sallallahu ‘alaihi wasallam).
