Ask for permission before sitting between two people.

The Prophet Muhammad (peace be upon him) taught us that it is important to show respect and ask for permission before sitting between two people. This hadith teaches us the importance of politeness and consideration when interacting with others. We should always remember to be courteous and polite, especially when we are in a group setting or around other people. By asking for permission, we are showing respect for the other person's space and privacy, which is an essential part of being a good Muslim.

The Prophet Muhammad also taught us that it is wrong to impose ourselves on others without their consent or approval. We should never assume that our presence will be welcomed by everyone in any given situation; instead, we should always take the time to ask if it would be alright if we join them or sit between them. This hadith reminds us of the importance of being mindful of our actions and words when interacting with others so as not to cause any offense or discomfort.
