Fatwa no. 2798:
Q: If Tawakkul (putting trust in Allah) does not mean that you should jump into a pool of water while you cannot swim, nor put yourself in danger by a physical movement without previous training, nor sit in a room full of insects without using insecticide and expose oneself to affliction of a disease, nor leave a drawer opened exposing its contents to loss, then what is the meaning of Tawakkul? We appreciate your guidance, and many thanks to you.
A: Tawakkul means that a person should put their trust in Allah (may He be Exalted) Alone. It is an obligatory act and one of the tenets of Iman (faith). Allah (may He be Exalted) says:Surah Al-Ma’idah, 5: 23 … and put your trust in Allâh if you are believers indeed. Tawakkul is one of the powerful moral means helping to achieve goals and fulfill purposes. However, a Muslim should combine it with other means, whether they are acts of `Ibadah (worship) like Du`a’ (supplication), Salah (Prayer), Sadaqah (voluntary charity) or maintaining the ties of kinship, or other material means which Allah has predestined that their effects follow from their causes like the examples mentioned by the questioner here. We should have Tawakkul to follow the way of Allah’s Messenger (peace be upon him) in this regard as he was the best person who had Tawakkul. He used to consider other appropriate material means along with his Tawakkul. So, whoever ignores the material means thinking that it is sufficient for them to have Tawakkul, contradict the way of Allah’s Messenger (peace be upon him). This type of Tawakkul is not permissible. Rather, it is recklessness and not a Shar`y (Islamically lawful) Tawakkul.
May Allah grant us success! May peace and blessings be upon our Prophet Muhammad, his family and Companions!
