Is there a hadith about the Eid greeting "taqabbalallahu minna wa minkum" on the morning of Eid, and what is its status?

Summary

The narration attributing this greeting to the Prophet is very weak, and the stronger view is that it is only a mauquf report from a companion. Nevertheless, the greeting is permissible based on other reports, graded hasan, showing that the companions greeted one another this way on Eid. Ibn Hajar al-Asqalani held it to be prescribed since the many reports can be relied on in matters of virtuous deeds, while al-Munziri considered it permissible, neither recommended nor an innovation.
