The level of sincerity when praying for success in final examinations is very high. The same applies when praying for protection from a mishap on a turbulent aircraft, cure from a serious illness or any extremely important matter. Some begin to say their daily prayers, dress appropriately & leave all sin because of the need of the moment. This should be the case at all times and not just when we are in dire need. Do we follow those who transgress and sin immediately upon passing their exams, or landing safely or being cured from disease etc yet moments ago they were weeping to their Maker whilst pleading their case, making every promise to obey His Commands? We are taught that those who gain closeness to the Almighty during times of ease shall indeed feel the closeness and assistance of the Almighty during times of difficulty or distress. He is STILL Most Forgiving Most Merciful & gives us much more than we deserve!
