Unlike humans, Allah will never place a burden on someone greater than he can bear.
Thus, whenever we face a challenge, put faith in ourselves that we are capable of overcoming it. We just have to be patient, try harder and know where to look for solution.
A locksmith will never create a lock without its key. Similarly, for every difficulty that we have, Allah has already created a solution that we will find eventually.
Pray not for a lighter burden, but rather for a stronger shoulder.
