What is the reference for the sun not rising when a single hair of Hazrat Fatima was discovered?

There is no such authentic incident. Allah Almighty does not change

His scheme of universe for such petty matters. These anecdotes are

concocted just as symbols to persuade people to remain pious and

virtuous. Hazrat Bibi Fatima RAU is the most beloved daughter of

our beloved Prophet Hazrat Muhammad (SAW) and the Chief of the

women of Paradise. She is already exalted beyond our imagination.

She does not require such incidents concocted by our illiterate

Khateebs.
