Sa’eed bin Jubayr narrates: Ibn Abbas died while in At-Ta’if. I witnessed his funeral and then a bird came that I had never seen before.
The bird entered the burial site and we looked and waited to see if it would come out, but we didn’t see it come out of the hole. When Ibn Abbas was laid in the ground, we heard this verse being recited at the edge of his grave but we didn’t know who recited it:
يا أيتها النفس المطمئنة ارجعي إلى ربك راضية مرضية فادخلي في عبادي وادخلي جنتي
O satisfied soul, return to your Lord content and with pleasure. Enter among My servants. Enter among My garden.
