Was the Prophet's prayer for Abu Hurairah to be loved by all believers confined to his lifetime, or is it eternal, and is inquiring about this matter considered backbiting Abu Hurairah?

Muslim narrated from Abu Hurayrah the Prophet's supplication for him and his mother to be loved among the believers, and that this supplication is general and continuous. This is indicated by the generality of the word "believers" in the Prophet's words, and "no believer was created" in Abu Hurayrah's words. Therefore, there is concern for the faith of whoever does not love Abu Hurayrah or does not acknowledge his narrations. And the question of the questioner about the Companion is not considered backbiting, but rather a request for a religious ruling.
