Reference for Taanit 47:10

ר' יהודה נשיאה גזר תעניתא בעי רחמי ולא אתא מיטרא אמר כמה איכא משמואל הרמתי ליהודה בן גמליאל אוי לו לדור שכן נתקע אוי לו למי שעלתה בימיו כך חלש דעתיה ואתא מיטרא

When his wife returned house she asked her daughter, What did your father bring home? She replied, He has put in the granary all that he had bought. She thereupon went to open the door of the granary and she found that it was so full of wheat that the wheat protruded through the hinges of the door-socket and the door would not open on account of this. The daughter then went to the Beth-Hamidrash and said to him [her father], Come and see what your Friend has done for you.
