Bayazid Bostami was a great saint. He was a very obedient boy. In his childhood, he was very obedient to his mother. Once, Bayazid was reading at his table. It was dead of night.His mother was in a deep sleep. She was ill. Suddenly, she woke up. She asked Bayazid to give her a glass of water. But there was not a drop of water in the pitcher. So Bayazid went to a distant fountain with the pitcher. Bayazid brought water for his mother. But by this time, Bayazid's mother was asleep again. Bayazid thought that he shouldn’t disturb his mother's sleep. So he kept standing beside his mother's bed the whole night with a glass of water. In the morning, Bayazid's mother woke up. She was surprised to see her son with a glass of water standing beside her bed. She understood the whole thing. Her heart was filled with a unique love for her son. She embraced her son and prayed for him from the core of her heart.
