Is it obligatory to surrender to fate and stop supplicating, or to continue supplicating with greater persistence, especially after seeing dreams that may indicate the difficulty of fulfilling one's hope, given the existence of hadiths stating that supplication changes fate?

He who fulfills the conditions for the acceptance of supplication and from whom its impediments are removed, his supplication will undoubtedly be answered. The forms of acceptance vary: either he is given what he asked for, or an equivalent evil is averted from him, or it is stored for him in the Hereafter. Impatience and abandoning supplication are among the impediments to its acceptance. Supplication changes destiny, yet it is part of destiny. Asking Allah to facilitate good wherever it may be is best. One should not rely on dreams; rather, one should ask Allah for their good and seek refuge in Him from their evil.
