When we go into the position of sujood we are asked to make dua. This is the closest position we are in to Allah.
Learn the beautiful supplications of Prophet Muhammad (PBUH). Learn to ask the Almighty using beautiful words that were used by our dear Prophet (PBUH) or that were mentioned by Allah in revelation. These are the most powerful words. We should try out best to use them to call out to Allah.
Whenever you are sad and feeling anxious and whenever there is uncertainty in your life, one of the best ways of benefitting yourself is to pray. Do two units of prayer and prolong the sujood.
