Hazrat Bayazeed ( رحمۃ اللہ علیہ ) was one of the saint. He used to consider service to mother great form of worship and her’s happiness a great blessing. One night his mother asked him a glass of water. He went carrying cup towards water pitcher that was a cold night, when he saw it was empty, and then he went to the river to fetch water. When he came back he saw his mother sleeping. He kept standing next to her holding glass of water although he was shivering of cold. When mother woke up and she saw he was standing holding the glass of water. She drank the water and said why you hold the glass of water and took so much hardship, why don’t you keep it nearby to me, I had it when I wake up. He replied you asked me water. I had a fear that when you woke up and don’t find me you will suffer on this reply, she got happy and prayed for him.
