Hisham bin Abi 'Abdullah al-Dastawa'i هشام بن أبي عبد الله الدستوائي · Chapters on Tafsir

"Ibn Abbas recited: This day, I have perfected your religion for you, completed My favor upon you, and have chosen for you Islam as your religion (5:3). And a Jew was with him who said: 'If this Ayah was revealed to us then we would have taken that day as a day of celebration.' So Ibn 'Abbas said: 'Indeed it was revealed on two 'Eids: On Friday, and on the Day of 'Arafah.'"
