Abu Huraira reported God’s messenger as saying that “There is no might and no power except in God” is a remedy for ninety-nine diseases, the lightest of which is anxiety.
Makhul quoted Abu Huraira as saying that God's messenger told him to say frequently “There is no might and no power except in God”, for it is part of the treasure of paradise. Makhul said that if anyone says, “There is no might and no power except in God” and “There is no refuge from God except by repairing to Him”, God will remove from him seventy categories of distress, the least of them being poverty.
Tirmidhi transmitted it, saying this is a tradition whose isnad is not fully connected, and Makhul did not hear anything from Abu Huraira.
He said that God’s messenger offered to guide him to a word from under the Throne which was part of the treasure of paradise, it being “There is no might and no power except in God.” He added that God most high says, "My servant has resigned and submitted himself to me."
Baihaqi transmitted the two traditions in ad-Da’awat al-kabir.
Anas said that, on coming upon a tree whose leaves were withered, God's messenger struck it with his staff, and the leaves were scattered. He then said that “Praise be to God; Glory be to God; There is no god but God; and God is most great” cause a man's sins to fall away just as the leaves of that tree were falling.
Tirmidhi transmitted it, saying this is a gharib tradition.
