As Mullah Nasruddin is widely known for his learning and wisdom, it happened once upon a time that he received a visit from a woman with a very worried expression.

“Mullah, you know so much – perhaps you can help me.”

“And what is the problem, sister?” he asked.

“My husband and I have been trying for a baby for years, but there is no success. We have taken herbs, said prayers – nothing works.”

Nasruddin stroked his beard to make himself appear extra-wise, and said, “Perhaps it is hereditary. Did your mother have the same problem?”
