And whatever calamities affect you, then that is due to your own hands that have earned, and He is Pardoning much.
The believer who remembers what is told in verse 4: 79 that good is from Allah, and evil is from yourself, keep the remembrance of Allah in all their standings, sittings, and lying as explained in verses 3: 190-191. Such believers are only utilizing Adhikr as the Shield and Safeguard against all calamities, disasters, diseases, and Hellfire, as explained in verses 5: 48. The hypocrites who have forgotten Allah, if they get any good, they boast that it is due to their knowledge and skill, and they are rejoicing with it. If any evil affects them, they blame and accuse others for it. Meanwhile, if the believer is affected by any evil or disaster, he, by identifying that it is due to his own mistake, turns to Lord Allah through Adhikr. See explanation 3: 101-102; 9: 80-82; 30: 41, and 35: 45.
