Was the supplication of Qunut part of the the Noble Quran and then abrogated?

Abrogation in the Qur’an is divided into three types: abrogation of recitation and ruling, abrogation of recitation without ruling (such as the verse of stoning), and abrogation of ruling without recitation. It has been authentically reported from Umar ibn al-Khattab, may Allah be pleased with him, that he used to perform qunut in the Fajr prayer with the supplication of "al-Khala' wal-Hafd," which were supplications commonly referred to as "the two surahs."

It has been authentically reported from Ibn Mas'ud and other Companions that these supplications were present in their copies of the Qur’an, and that they were among what was revealed from the Qur’an and then their recitation was abrogated. Some Companions continued to recite them in their qunut due to the supplication and praise they contained.

The utmost conclusion is that this supplication was part of the Qur’an, then its recitation was abrogated by the consensus of the Companions. This is not considered a flaw in the Qur’an; rather, it is part of the well-known and accepted principle of abrogation in the religion.
