There was once a great man, anmed Sharfuddin Yahya. He cared a lot for his parents when he was a boy. He was obedient and kind to them.
One night, his mother was thirsty and asked Sharfuddin for a glass of water. When Sharfuddin came to his mother with the glass of water, he found her asleep.
He did not think it wise to disturb his mother's sleep. So, he kept standing there with the glass in his hand until his mother awoke.
His mother opened her eyes after a few hours and found Sharfuddin standing beside her with the glass of water.
She asked him, "My dear son, have you been standing all this time?">
Sharfuddin said, "Yes mother, I have been waiting fo you to wake up, to give you a glass of water."
Sharfuddin's mother was very pleased with him. She blessed him and prayed to Allah to make Sharfuddin a great man. When he grew up, Sharfuddin was really a very great man of his time.
Allah (ta'ala) commands us to be good and kind to our parents. Here is a du'a that you can learn to make du'a for them:
Rab-bir ham-huma kama Rabba-yani Sagheera
My Lord! Place on them Your Mercy even as they cherished me in childhood
[surah bani Isra'il; 17: 2]
