A rare woman with two pearls

It is rare that a woman came to Ibn Sirin and she said, I saw two pearls in my room, one of which is greater than the other, so my sister asked me to give one of the two pearls, and I gave her the youngest. He said if you believed your vision, you learned two surahs, one of which is longer than the other, and your sister taught the short, she said, is right .
