I have two different questions that seem very important to me. 1 - I got a diploma of management a year ago. While I was in the exam of the third year one of my classmates asked me to show her how to answer some questions and I did ; I have also took an answer from her. Now, I really regret what I did. I feel that I don't have the right to use the diploma. So, I'm asking about what I must do to correct this mistake. Do I really have the right to use the diploma? What must I do with this person knowing that she 's working now and don't even think about that? So, what must I do? 2 - While I was alone I thought just for a while that God doesn't exist. I felt as if I became an unbeliever for a moment. What can you say about that. Thank you.

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

Know that the feelings that come to your mind are nothing but devil's insinuation. He (the devil) always tries to spoil your religion, faith and even your life. Therefore, be attentive and do not be a subject to such feelings. Seek refuge of Allah to protect you from Satan. Moreover, keep thinking about the creatures of Allah and work hard to get rid of bad feelings, and surely Allah will remove them.
