What is the wisdom behind specifying certain times and conditions for the acceptance of supplication – such as the prayer of the oppressed – even though every supplication is answered according to specific conditions?

By Allah's will, supplications are answered if their conditions are met and their impediments are absent. The response takes one of three forms: the fulfillment of what was requested, the storage of reward in the Hereafter, or the warding off of harm from the supplicant. As stated in the noble Hadith: “There is no Muslim who supplicates with a supplication in which there is no sin or cutting off of kinship ties, but Allah will grant him one of three things: either his supplication will be hastened for him, or He will store it for him in the Hereafter, or He will avert from him an evil equivalent to it.”

Among the reasons for the acceptance of supplications are: its being made during a time of acceptance (such as the last third of the night, and between the Adhan and Iqamah), or its being made by an oppressed person, a traveler, or a parent for their child, or the supplicant being insistent. Furthermore, good food and not supplicating for sin or cutting off kinship ties are essential conditions.

Times of acceptance are a contributing factor to the supplication being answered, not a condition. Supplications made during these times are closer to being answered. However, a supplication may sometimes not be answered despite being made at a time of acceptance, either due to the absence of a condition (like good food) or the presence of an impediment (like hastiness), or because Allah Almighty wishes to delay the fulfillment of the request for the servant's benefit.
