I carried that thought with me to the examination centre, committed to doing it. However, when I got there, I mentally pushed it aside to execute my other secular duties.
First, I checked to see if all my students were present, except those I expected to be absent. I also checked to see if the question paper had any errors. After doing this I checked the questions to determine how many possible interpretations could be had of my examination questions.
Finally, I remembered the prayer. I stood and closed my eyes and petitioned G-d in whispers, I heard snickering or laughing from 2 of the invigilators in front of me.
In the petition, I asked G-d to be gracious and merciful to the students and to cause them recall what they studied, learnt and read. I also petitioned that they would interpret the questions properly and read them carefully, that their answers would be relevant and match my expectations.
I also asked that God have pity on the students. I referred him to his heart of compassion that he had, wherein he was not willing that any perish but that all would have eternal life. I mentioned to G-d that this is similar to my situation as a lecturer, as I too had no desire that my students fail but that all should pass.
After petitioning G-d on the behalf of the students, I left the examination centre and returned 2 hrs after, when the students were leaving. One female student who was just leaving her seat walked over to me and said:
"Sir, I thank you for the prayer. I could not think until I saw you do what you did."
I knew then that G-d had used me and answered the prayer.
