آمَنَّا بِهِ وَعَلَيْهِ تَوَكَّلْنَا ۖ فَسَتَعْلَمُونَ مَنْ هُوَ فِي ضَلَالٍ مُّبِينٍ
Say, “He is the Most Merciful; we have believed in Him, and upon Him we have relied. And you will [come to] know who it is that is in clear error.” | QS 67:29
Surat Aţ-Ţalāq – سورة الطلاق
وَمَن يَتَوَكَّلْ عَلَى اللَّهِ فَهُوَ حَسْبُهُ ۚ إِنَّ اللَّهَ بَالِغُ أَمْرِهِ ۚ قَدْ جَعَلَ اللَّهُ لِكُلِّ شَيْءٍ قَدْرًا
And will provide for him from where he does not expect. And whoever relies upon Allah – then He is sufficient for him. Indeed, Allah will accomplish His purpose. Allah has already set for everything a [decreed] extent. | QS 65:3
The root of Tawakkul is ‘reliance’ or ‘dependence’. We say that we depend on Allah SWT for everything, and place reliance on Him. The reality of Tawakkul is that we place our trust and reliance on Allah SWT in terms of both our worldly affairs, as well as our Deen, by utilizing our visceral, or tangible means of attaining that which we want to attain.
Tawakkul, therefore, involves belief, dependence, and action. This is because in order to gain at least some level of Tawakkul, the slave needs to be aware of the fact that all the matters of this world and the Hereafter lie in the Hands of Allah SWT. Nothing occurs except by His Wills & Permissions.
