I have been getting waswasa as to the existence of God and my salah feels monotonous and dead due to these waswasa. I have tried to talk to Allah on every last sujud to see if it helps. How can I bring my heart to ease? Is there a Dua I can recite to see Imam al Mahdi (atfs) (I have tried a few things but to no avail, perhaps due to my sins)? The cause of these doubts and whisperings may be aqeeda- related and also related to my largely company.

I recommend the following:

1- Increase your Islamic knowledge. The best way to combat doubts is to strengthen your knowledge. Take only English seminary classes. They are very helpful.

2- See this video:

3- Recite these Du’as:

آمنت بالله وبرسوله مخلصاً له الدين

هو الأوّل والآخر والظاهر والباطن وهو بكلّ شيء عليم

توكّلت على الحيّ الذي لا يموت والحمد لله الذي لم يتّخذ ولداّ ولم يكن له شريك في الملك ولم يكن له وليّ من الذلّ وكبّره تكبيراً

لا إله إلّا الله محمّد رسول الله عليّ أمير المؤمنين

أعوذ بالله القويّ من الشيطان الغوي وأعوذ بمحمّد صلى الله عليه وآله الرضي من شرّ ما قدر وقضي وأعوذ باله الناس من شرّ الجنّة والناس أجمعين

4- Wash head with Sidr water

Insha’Allah a combination of these will help significantly.
