Muhammad bin Muhammad al-Judhu'i, the judge, said: I heard al-Abbas bin al-Walid al-Narsi say: I asked Abu Ubaydah Ma'mar bin al-Muthanna about the meaning of the saying "Indeed a state comes over my heart," but he did not explain it to me; and I asked al-Asma'i as well, but he too did not explain it.
