The imam recited half a surah after al-Fatihah in the first rak'ah of the Fajr prayer, then prostrated, then stood up and completed the surah. Is there a basis for his action?

Question:
He asks and says: The imam prostrated in the first rak'ah of the Fajr prayer after reciting al-Fatihah and half a surah, then stood up and completed the surah and bowed. The question here is why the imam acted in this manner? And what is the ruling? May Allah reward you with good. The imam prostrated in the first rak'ah of the Fajr prayer after reciting al-Fatihah and half the surah, then stood up and completed the surah, then bowed, and so on. The question here is why the imam acted in this manner? And what is the ruling?

Answer:
There is nothing wrong with that. There is nothing wrong with the imam, or any praying person—whether imam, ma'mum, or praying alone—dividing a surah between the two rak'ahs, reciting the beginning in the first rak'ah and the end in the second rak'ah. There is nothing wrong with that, especially if the surah is long. There is nothing wrong with dividing it between the two rak'ahs. Praise be to Allah. May Allah reward you with good.
