Sa'id bin Jubayr said: Sayyiduna Ibn Abbas (may Allah be pleased with them both) died in Ta'if, and I attended his funeral. A white bird came, the like of which had never been seen before, until it entered his bier, and then it was not seen coming out of it. When he was buried, this verse was recited at the edge of the grave, and we could not tell who recited it: "O soul at rest! Return to your Lord, well-pleased and well-pleasing. So enter among My servants, and enter My Paradise" [Surah al-Fajr: 27-28].
