Ibn `Abbas used to call this chapter, `Surah Bani An-Nadir.' Sa`id bin Mansur recorded that Sa`id bin Jubayr said, "I asked Ibn `Abbas about Surat Al-Hashr and he said, `It was revealed about Bani An-Nadir.''' Al-Bukhari and Muslim recorded it using another chain of narration from Ibn `Abbas. Al-Bukhari also recorded it from Abu `Awanah, from Abu Bishr from Sa`id bin Jubayr, who said, "I asked Ibn `Abbas, `Surat Al-Hashr' He said, `Surah Bani An-Nadir.'''
In the Name of Allah, the Most Gracious, the Most Merciful.
