219. This verse was revealed long after the revelation of the rest of this surah. According to certain traditions, this verse was the very last Qur'anic verse to be revealed. (For these traditions, see Ibn Kathir's comments on this verse - Ed.) Even if this is disputed, it shows at least that this verse was revealed in 9 A.H., whereas the Muslims had been reciting the present surah, al-Nisa, for quite some time before that. It was for this reason that this verse was not included among the verses relating to inheritance mentioned at the beginning of the surah, but was attached to it at the end as an appendix.
