I understand that you are wary of superstitious thinking.
Now, I have no doubt that evil spirits are at work in this world, but to live in constant fear of them renders you helpless and imprisoned by fear.
Remember, that instilling fear in our hearts and doubt in God's power is one of Satan's greatest strategies!
If I was you I would pray for God's protection on you and your loved ones and trust in Him.
When I am fearful I find Ephesians 6:10-18 very useful.
(As a Muslim you may not agree with all of it, but you may find it helpful nonetheless, in terms of putting yourself mentally and spiritually under the protection of God. Perhaps there are similar passages in the Qu'ran, which you can draw strength from.)
Finally, be strong in the Lord and in his mighty power. Put on the full armor of God so that you can take your stand against the devil's schemes. For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground.
