The ruling on reciting al-Fatihah behind the imam in the loud prayers

Question:
Honorable Shaykh. Those among the scholars who held that it is obligatory to recite al-Fatihah behind the imam in the loud prayers cited as evidence what al-Tirmidhi narrated from 'Ubadah: "Perhaps you recite it behind your imam. Do not do so except with al-Fatihah, the opening of the Book." However, this hadith came through the narration of Makhul from Mahmud ibn al-Rabi' from 'Ubadah, and Makhul did not hear from Mahmud, so it is a broken chain. What is your opinion? Does it support the position held by these scholars?

Answer:
The primary evidence in this chapter is the hadith of 'Ubadah . . The hadith "Why should I contend with the Qur'an? Why should I contend with the Qur'an? Perhaps you recite behind your imam" refers to this, so it supports the hadith of 'Ubadah, which is the foundation of the chapter. The foundation of the chapter is the hadith of 'Ubadah ibn al-Samit : "There is no prayer..." The negation here refers to the lawful prayer, which is the first thing that comes to mind. Even if some say that the implied meaning is "there is no complete prayer, no complete prayer," this is based on the opinion of those who consider the prayer valid without reciting the opening of the Book, but who require reciting whatever is easy, even if it is not al-Fatihah, as is well known among the Hanafis.
