What is the authenticity of the hadith "What is permissible for a prophet is permissible for a saint"?

The statement, "What is affirmed for a prophet is permissible for a saint," is not a raised hadith (a saying or act of the Prophet Muhammad reported by his companions), but rather a saying of some scholars. It means that every miracle found in a prophet may occur as a karamah (a miraculous feat or divine favor) for a saint. This statement is not to be taken as absolute, but rather with exceptions for what was used as a challenge by some prophets, for saints cannot attain the like of it. It is part of the creed of Ahl al-Sunnah wal-Jama'ah (Sunni Muslims) to affirm the karamat of saints, and they believe that the karamah of a saint is a miracle of his prophet, because the saint attained it through his adherence to his prophet.
