There is a common saying that if there is a spider web in the house , there is a shortage. It can be seen that many people are involved in the argument. Many take it for granted. But there is no basis for this in Islamic law. Therefore, Islamic scholars have considered the statement that there is scarcity in spider webs as unrealistic. But yes , cleanliness is an important provision of Islam. Islam attaches great importance to cleanliness. God loves clean people. Some philosophers are of the opinion that if there is a spider's web in the house , then there is a shortage . And the result of laziness is poverty. From this it has become common to say that if there is a spider web in the house, there is a shortage. Many people forbid killing spiders. The theologians are of the opinion that if a spider is harmful or poisonous in nature, then it is permissible to kill it. But if it is not harmful then it is better to throw it away from the house without killing it.
