1. Doubts can come to any one and it does not mean that you believe in it or you are a bad person just because of the doubts or thoughts in your mind as far as you do not believe in it. Doubts are from Shaitan who tries to disturb the believers or at least make them feel uncomfortable. 

2. Don't suppress any question comes to your mind and counter it by the strongest evidence which we have we have in every field and in any matter. Never feel frightened from doubts and be sure that it will vanish as soon as you look at the evidence.

3. Put your questions to reliable scholars who are able to respond properly.

4. Your feeling of uneasiness from the doubts is an evidence that you are a good person and you are not happy with these doubts. You just need to counter the doubts with the evidence which we have for every mater.

5. You should never neglect or postpone tackling your doubts to get them cleared as the best way do deal with doubts is to discuss them according to the evidence. You will easily see that doubts are based on misunderstanding or misinformation etc. Usually, those who respond with authentic evidence get out of the doubts with stronger faith and more clear surety in the True Faith of Islam.

6. Good deeds are always good, but it can never be enough if the faith is wrong, as we read in Quran always (Those who believe (in the Truth) and do good).

7. Always seek help from Allah (SW) to protect you from the whispering of Shaitans (And say: My Lord, I seek refuge with you from the whisperings of the devils) (Sura 23, Verse 97). Devils run away when you recite Estighfaar (ASTAGHFIRULLAH RABBI WA ATOOBU ELAYH) and (LA HAWLA WALA QOWWATA ILLA BILLAH) and (LAA ILAAHA ILLALLAH).

Wassalam.
