Ibn Al-Qayyim said that “the effectiveness of these surahs is great to repel magic, evil eye, and the rest of the evils and the need for a slave to seek Allah’s protection from these two surahs is greater than his need for self, eating, driking, and wearing dress” (Al-Fawwaid, 2/426)
Why do we worry? When Allah has promised to take care of the affairs of those who put thier trust in Him? Worrying over matters we have no control over is from Shaytaan. Rather, put full trust in Allah and keep telling yourselves that Allah is controlling everything! Make Dua'a.
