The majority of scholars see that al-Fatiha is a pillar of the prayer, while according to the Hanafis it is obligatory, and according to the majority it is a pillar.
But also, this majority who said it is necessary, said it can be dropped.
If someone comes and the imam is in ruku', al-Fatiha is dropped for him.
If he catches the imam while he is in ruku', then this pillar is dropped for him.
He bows with the imam and completes his prayer, due to the narration: If you come to the imam while he is in ruku', then bow and count it.
As a rak'ah, and this was the view of al-Bukhari.
And Subki said that the rak'ah is not valid unless you catch al-Fatiha.
You must recite al-Fatiha, and this was also the fatwa of Shaykh Muqbil al-Wadi'i.
He said all the narrations that mention catching
the bowing as catching the rak'ah without reciting al-Fatiha, he says: either authentic but not explicit, or explicit but not authentic.
In any case, this issue is disputed, and the majority, yes, that a person catches the.
bowing even if he missed al-Fatiha, and knowledge is with Allah, the Exalted and Most High.
