It was narrated that 'Abdullah said: "Whoever has doubt, or is not sure, let him estimate what is correct, then let him prostrate twice".
It also reminds us of the importance of prayer in our lives; no matter what situation or difficulty we face, prayer can help us find peace and solace within ourselves. By offering two prostrations after making an educated guess on a difficult matter, it shows that we are grateful for any guidance or help that Allah has provided us with during this time of uncertainty.
