:: just like the oceans needs the waves ::

يَا أَيُّهَا النَّاسُ أَنتُمُ الْفُقَرَاء إِلَى اللَّهِ وَاللَّهُ هُوَ الْغَنِيُّ الْحَمِيدُ

Sahl at-Tustari (rahimahullah) said:
“Gratitude to Allah is not to disobey Him with His favours. The whole body is from the favours of Allah and His giving, so do not disobey Him with any of it.”
