What did Ibn Taymiyyah, Ibn al-Qayyim, and al-Albani say about abrogation (al-nāsikh wal-mansūkh), and where can their statements on this be found, and how many verses are abrogated?

The abrogated verses in the Holy Qur’an, according to Al-Suyuti, are twenty verses, though some have disagreed with him on this. These verses can be searched for in the works of major scholars, available on discs or online, by looking for words such as "abrogation" (النسخ) or "Whatever verse We abrogate" (ما ننسخ من آية). For further expansion, it is advisable to consult books on abrogation (Nasikh and Mansukh), Qur’anic sciences, and books of Tafsir (exegesis), as well as Sheikh Al-Shanqeeti’s commentary on Al-Suyuti’s poetic composition, which is found with Adwa’ Al-Bayan.
