Imam Baqir (a.s) said: “Some people suffered at the time of the Prophet Hud (a.s). They went to him to ask him to pray to God to send down rain from His Mercy. Then a vulgar shrew came out of Hud's house and said: “Why does Hud not say this prayer for himself?” The people asked her to take them to Hud. She told them that he was on the farm watering it. They went there and saw that after Hud watered each part of the farm, he stood up and said two units of prayer. Then Hud noticed them and asked: “What do you want?” They said: “We came to you to ask for something, and saw something even more amazing. We saw a vulgar shrew leave your house and yell at us.” He said: “She is my wife and I hope that she lives a long life.” They said: “O' Prophet of God! Why do you wish her to live a long life?” He said: “Because there is someone to bother every believer, and I thank God that He has established a person who is subject to me to be the one to bother me. If it was no so, someone worse than her would bother me.”
