Q: Is this Hadith authentic? “Whoever reads Surah Ikhlas 100,000 times would have bought himself from Allah, and a caller from Allah will announce in heaven and on earth: ‘verily, so-and-so has been set free by Allah, so whoever owes him anything, let him claim it from Allah.'”
A: We do not know.
And Allah Ta’ala (الله تعالى) knows best.
