How can one reconcile the certainty that supplications will be answered and that Allah is Modest and would not turn away the hands of His servant empty, with the possibility of a delayed response until the Afterlife or the supplication not being answered for other reasons, especially considering the saying of Umar ibn al-Khattab, may Allah be pleased with him: "If a person is inspired to supplicate, then the answer is with it"?

There is no contradiction between the command to supplicate with certainty and the rejection of the supplication, the delay of the response, or Allah's shyness to turn away the servant's hands empty. The Prophet, peace and blessings be upon him, commanded supplication with certainty of response. The reason for non-response may be due to the presence of impediments, such as not seeking lawful earnings, supplicating for a sin, or being impatient. This does not negate Allah's shyness to turn away the servant's hands if the supplication fulfills the conditions for response.

The apparent non-response does not mean absolute non-response, for the response comes in one of three ways: expediting the supplication, reserving it for the Hereafter, or averting evil from the supplicant similar to it. The rule is that every supplication that meets the conditions will have a response. The problem arises from confining the response solely to the fulfillment of what is requested, whereas the response is broader than that. Evil may be averted from the servant without him knowing, or the reward may be delayed for him in the Hereafter. It is advised not to dwell on the idea of non-response, as it stems from a lack of certainty and is one of the impediments to response.
