Tafsir al-Baghawi                                                        تفسیر البغوی                            

عَنِ ابْنِ عَبَّاسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: إِذَا زُلْزِلَتِ الْأَرْضُ تَعْدِلُ نِصْفَ الْقُرْآنِ،  قُلْ هُوَ اللَّهُ أَحَدٌ ، تَعْدِلُ ثُلْثَ الْقُرْآنِ،  قُلْ يَا أَيُّهَا الْكَافِرُونَ  تَعْدِلُ رُبْعَ الْقُرْآنِ

Sayyiduna Ibn Abbas – may Allah be pleased with them – reported that the Holy Prophet – may Allah send peace and blessings upon him – has stated:  Surah Al-Zilzaal is one-half of the Quran, Surah Al-Ikhlas is one-third of the Quran and Surah Al-Kafiroon is one-fourth of the Quran.
