Is there an authentic Hadith that specifies the virtue of reciting the last verses of Surat Al-Hashr or supplicating with them, and does this virtue include the last 3, 4, or 10 verses of it, or are the narrations mentioned in that regard weak and not to be acted upon?

Several hadiths have been narrated regarding the virtues of the last verses of Surat Al-Hashr, but most of them are weak or not authentically established. Among these hadiths is the one that states, "Whoever says three times in the morning: 'I seek refuge with Allah, the All-Hearing, the All-Knowing, from the accursed Satan,' and recites three verses from the end of Surat Al-Hashr, Allah will entrust seventy thousand angels to pray for him until the evening..." This hadith is gharib (rare) and has been deemed weak by Al-Nawawi, Al-Albani, and others. Other weak hadiths have also been narrated about the virtue of reciting the end of Surat Al-Hashr for martyrdom, forgiveness of sins, or that it contains Allah's Greatest Name. Some narrations suggest using verses from the end of the surah as a ruqyah for headaches or healing from illnesses, but their chains of transmission are weak and unknown.
