Like walking in sand..

‏قال ابن مسعود «رضي الله عنه» :

المخلص لربه كالماشي على الرمل لا تسمع خطواته ولكن ترى آثاره

[جامع العلوم والحكم 302]

Ibn Masood رضي الله عنه said:

The one who is sincere to his lord is like a person who walks on sand. You don’t hear his footsteps but you can see his traces.
