What is the fate of a believer's supplications that were not answered in this world, and will they be compensated for in the Afterlife?

The one who said, "Inform me," is Al-Hakim, who said about the hadith (definition): "Al-Fadl ibn 'Isa Al-Raqashi was unique in narrating it from Muhammad ibn Al-Munkadir, and Al-Fadl ibn 'Isa is in a position where no fabrication is to be imagined." Al-Albani deemed the hadith weak due to the weakness of Al-Raqashi. The authentic hadith suffices in its place: "There is no Muslim who supplicates with a supplication in which there is no sin or severing of family ties, except that Allah will grant him one of three things: either his supplication will be answered promptly, or it will be stored for him in the Hereafter, or evil will be averted from him in proportion to it."
