The ruling on the imam reading a single verse after al-Fatihah, such as (Alif Lam Mim)

Question:
Muhammad al-Shaqari says: Shaykh, if I read one verse after al-Fatihah, such as Alif Lam Mim, and then bow, and in the second rak'ah I read another verse after Surat al-Fatihah, is this action valid, given that I am the imam of a congregation?

Answer:
My brother, the imam of the congregation reads and lets the congregation hear whatever is easy for him of the Qur'an. He does not shorten the recitation, nor does he read a verse that does not stand alone in meaning. Alif Lam Mim does not stand alone in meaning except with the mention of what follows it, along with the recitation of what follows it. So a verse that does not stand alone in meaning is not sufficient. It is necessary that the verse stand alone in meaning. And as we mentioned, the imam of the congregation does not withhold from them hearing something of the Qur'an so that their hearts may be elevated, and so that they may benefit and take admonition. Especially in Fajr. In Fajr, it is the sunnah (recommended practice) for the recitation to be long, because Allah named it "the Qur'an of Fajr" in His saying, the Exalted: "And the Qur'an of Fajr," meaning the Fajr prayer. That is, the angels attend it, so the recitation is lengthened. And the Prophet (peace and blessings be upon him) used to recite between seventy and one hundred verses in the Fajr prayer, so the recitation in the Fajr prayer is long. Yes.
