Answer:
All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad 
is His slave and Messenger.
and him speaking after his death was actually cited by Ibn Katheer in Al-Bidaayah wan-Nihaayah, and he mentioned that it is a well-known account that was reported by many authentic sources, and he mentioned that some of those accounts were assessed as authentic by Al-Haakim and Al-Bayhaqi.
Ibn Hajar said in Tahtheeb At-Tahtheeb: “...and he was mentioned as one of those present at the Battle of Badr and [it was reported] that he was the one who spoke after death by Ibn Sa’d, Ibn Abi Haatim, At-Tirmithi, Ya’qoob ibn Sufyaan, Al-Baghawi, At-Tabari, Abu Nu’aym and others.” Therefore, it seems that this story has been verified by the scholars.
This story demonstrates the power of Allaah Almighty Who is Omnipotent, and Who is able to do all things. It also indicates the virtue of this Companion as Allaah honored him with this supernatural event.
Al-Haafith Ibn Hajar said in the biography of Zayd: “His father was present at the Battle of Uhud, and he himself was present at the Battle of Badr. Al-Bukhari and others mentioned that he was the one who spoke after death.”
Allaah Knows best.
