An imam who habitually reads a portion of a long surah in the first rak'ah of the Fajr prayer and a portion of it in the second

Question:
He says: Honorable Shaykh, may Allah grant you success. An imam reads a portion of a long surah in the first rak'ah of the Fajr prayer, and a surah from the short surahs of the final part of the Qur'an in the second rak'ah, and this is almost a habit of his. What is the ruling on this action?

Answer:
It is better for him to divide it if the surah is long, dividing it between the two rak'ahs. If the surah is short, he may read another surah in the second rak'ah, and there is nothing wrong with that. However, if it is long, he should divide it between the two rak'ahs.
