"At-Tawakkul ‘ala Allah"is the Islamic concept of complete reliance on Allah or "trusting in Allah's plan." The root word in Arabic is وَكَلَ (wakala) which means to entrust, charge or authorize. Allah is al-Wakeel, the Disposer of Affairs, the One entrusted, relied upon, depended upon and sufficient to take care of all matters.
Difference between tawakkul and tawaakul
Tawakkul means putting trust in Allah while also implementing the means that have been permitted. Scholars have made an important distinction between tawakkul (توكل) and tawaakul (تواكل). Tawakkul is a Muslim's trust and acceptance of the divine will, which no one knows, understands or controls except Allah.
The meaning of tawaakul, on the other hand, comprises elements of laziness, inability, a resigned, careless attitude.
