Hadhrat Jaabir (RA) passed the Fatwaa that Rasulullaah (sallAllaahu-alayhi-wa-sallam) referred to the person performing salaah alone when he said that salaah which cannot be made without Surah Faatiha. Rasulullaah (sallAllaahu-alayhi-wa-sallam) did not refer to the Muqtadi when he said this. Salaah will be in order when a Muqtadi does not recite Surah Faatiha. [Tirmidhi, Vol.1 Pg.42 and Mu'atta of Imaam Maalik, Pg.105]

Based on this statement of Hadhrat Jaabir (RA), Imaam Ahmed (A.R) [who was the Ustaadh (teacher) of Imaam Bukhari (A.R)] issued the ruling that the person performing salaah by himself is referred to in the hadith: "There is no salaah for the one who does not recite Faatihatul Kitaab i.e. Surah Faatiha". [Tirmidhi Vol.1 Pg.42] Hadhrat Sufyaan bin Uyayna (A.R) has issued the same Fatwaa.
