What a difference trial. May God help you and be with you every step of the way.
Some recommendations:
1- Tell them prayer improves your mental health. It motivates you to study more, it gives you a positive mood, and it makes you more energetic.
2- Tell them prayer makes you more humble and more willing to help others.
3- Tell them prayer is a type of meditation and it brings you peace and happiness.
4- Tell the students who pray are happier than those who don’t. A study by Harvard proved this.
Hopefully some of these points will convince them.
