Question:
I have been told that the funeral prayer of our prophet ﷺ was first prayed by Allah then the angels and then the sahabas, is this true.
Answer:
In the name of Allah, Most Compassionate, Most Merciful,
We are unaware of such a narration. If in future someone attributes something to the Prophet 
, ask the person for a reference and inshaaAllah we will check it up to see if it meets the criteria of Authentic narrations and if not what category of narration it would fall under.
And Allah Ta’ala knows best
