Devotion to mother

Bayazid was a small boy. One night he was studying by the side of the bed of his ailing mother. All on a sudden, his mother woke up. She felt very thirsty. She told her son to give her a glass of water.
But there was no water at home. Taking a pitcher Bayazid went to a distant fountain to fetch water. He came back with water and found his mother asleep. He did not awake her. Keeping a glass of water in a hand, he remained standing still beside his mother's bed. He was waiting for his mother's awakening. But she was in sound sleep.
When it was dawn, Bayazid's mother awoke and instantly discovered her son standing beside her bed with a glass of water in hand. She wondered for a moment. Then she could realize the fact. She could not control her son with deep love and blessed her from the core of her heart.
