Is reading from the long or medium-length surahs of the final part of the Qur'an divided between the two rak'ahs, or is one surah read in each rak'ah?

Question:
Honorable Shaykh, may Allah grant you success. He says: Is reading a surah from the long or medium-length surahs of the final part of the Qur'an divided between the two rak'ahs, or is one surah read in each rak'ah?

Answer:
If the surah is long, there is no harm in dividing it between the two rak'ahs. However, if it is of medium length, he should read it all in the first rak'ah and read a second surah in the second rak'ah; this is the best and it is the sunnah (recommended practice). But some imams, if they read Surat al-Ikhlas, it takes an hour because they repeat and prolong and break up the recitation. The recitation varies; a smooth, good recitation like the recitation of the Messenger (peace and blessings be upon him) is fine. But dragging out the words, which they call tajwid (the rules of Qur'anic recitation), is a mistake.
