Keep dogs only when needed for farming or herding purposes.

This hadith is about the consequences of keeping an unnecessary dog. According to the Prophet Muhammad, if someone keeps a dog that they do not need for farming or herding, then one qirat will be deducted from their good deeds each day. A qirat is an amount of reward or punishment that Allah gives us in return for our actions. Therefore, this hadith teaches us that we should only keep dogs if we have a purpose for them and not just as pets. We should also remember that all our actions are being recorded by Allah and He will reward us accordingly on the Day of Judgment.
