Ibn ‘Abbas said that a Jew who was with him when he recited, “Today I have perfected for you your religion . . ."(Al-Qur’an; 5:3) remarked, “If this verse had been revealed to us we would have made it a festival." Ibn ‘Abbas replied, “It was revealed on a day which contained two festivals, on a Friday and on the day of ‘Arafa."
Tirmidhi transmitted it and said this is a hasan gharib tradition.
‘Abdallah b. ‘Amr reported God's Messenger as saying, “Any Muslim who dies on Friday or on Thursday night will be protected by God from the testing in the grave."

Anas said that when Rajab came God’s Messenger said, “O God, bless us in Rajab and Sha'ban and bring us to Ramadan.” He also quoted him as saying, “Thursday night is a very bright night and Friday is a shining day.”
Abud Darda’ reported God’s Messenger as saying, “Invoke many blessings on me on Friday for it is witnessed. The angels are present on it, and no one will invoke a blessing on me without his blessing being submitted to me till he stops." He said that he asked whether that applied also after his death, and he replied, “God has prohibited the earth from consuming the bodies of the prophets;" so God’s prophet is alive and given provision.
