All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.
As for the Hadeeth narrated by Abu Hurayrah its chain of narration is authentic and it is Mawqoof (a Hadeeth narrated by a Companion in which the chain of narration does not reach the Prophet, sallallaahu ‘alayhi wa sallam), in the sense that it is not attributed to the Prophet, sallallaahu ‘alayhi wa sallam. Shaykh Al-Albaani said about it in his book Ahkaam Al-Janaa'iz: "Its chain of narration as Mawqoof is very authentic."
Besides, the narrations that our dear questioner mentioned from the Companions he named are authentic. It was also proved that Ibn ‘Umar did not recite Al-Faatihah in Funeral prayer. It was narrated from Naafi’ that ‘Abdullaah ibn ‘Umar did not recite Quran in the Funeral prayer. [Maalik; Al-Muwatta']
Ibn Battaal said in Sharh Al-Bukhari: "Amongst those who did not recite Quran in the funeral prayer and denounced that were ‘Umar ibn Al-Khattaab, Ali ibn Abi Taalib, Ibn ‘Umar and Abu Hurayrah ." [End quote]
Although Hanafi scholars viewed that it dislike to recite Al-Faatihah in funeral prayer, they allowed reciting it as a form of supplication and praise (to Allaah). In this way, they interpreted the authentic narrations mentioned regarding reciting it. Al-Kaasaan'i Al-Hanafi said in Badaai' As-Sanaai': "Nothing of the Quran should be recited in the Funeral prayer and according to us, if Al-Faatihah was recited as a kind of supplication and praise, then this will not be disliked."

In Al-Mabsoot, As-Sarakhsi said: "To interpret the Hadeeth of Jaabir we say that he recited it as a kind of praise and not as reciting Quran." [End quote]
