Treasury of Sugar
When the Chishti Baba Fariduddin Masud Shakarganj was small, his mother gave him sugar as a reward for doing his salat properly. She would hide some sugar under his prayer-carpet, then give it to Farid after he had completed his prayer. One day his mother went to the market, and he had to pray alone. After his prayer he lifted the carpet and found a great supply of sugar a miraculous gift of God. His mother returned home, and when she saw what had happened, she was astonished, and gave him the name Shakar Ganj Treasury of Sugar.
