He said: Yes, if you wish.
He said: two thirds?

Reported by al-Bayhaqi and a group, and its chain of narration is good, and narrators are trustoworthy.
Hadith Fifteen: From Abdullah bin Masud (Allah be pleased with him) said: ‘The Messenger of Allah (Allah be pleased with him said): The closest people to me on the day of judgement will be those of them who send the most blessings upon me’.
Reported by Abu Isa al-Tirmidhi and Ibn Abi Asim
 Al-Bayhaqi in ‘al-Shuab’ (2772) the chain of narration contains Amr bin Shimr, who is abandoned and accused, al-Bayhaqi indicated towards this matter in his ‘Maarifah al-Sunan wal-Athar’ (4/420) where he said: ‘It has reached us with a weak chain in a marfu form, and Allah knows best”.
There are numerous narrations with a similar meaning, they strengthen each other, see ‘Al-Qawl al-Badi’ (p.235) and ‘Nur al-Lumah fi Khasais Yawm al-Jumah’ of al-Suyuti. Allah have mercy on both of them.
Also reported by Ibn Abi Asim (60) al-Bayhaqi in ‘al-Shuab’ (1478) in a mursal form from Muhammad bin Yahya bin Hibban who said: This is a good mursal narration. Al-Sakhawi indicated (p.176) that the grading of Hasan from al-Mundhiri and al-Haithami were due to the supporting narrations.
Also reported by Ibn Abi Shaibah (11836) al-Bukhari in ‘Tarikh al-Kabir’ (559) Abu Yaala (501) Ibn Hibban ( 911) al-Tabarani in ‘al-Kabir’ (9800) al-Bayhaqi in ‘Shuab al-Iman’ (1462) al-Khatib in ‘al-Jami’ (1305) from the route of al-Tirmidhi and reported by al-Baghawi in ‘Sharh al-Sunnah’ (686).
