Ask for permission before entering into a transaction or making a marriage proposal when your brother has already done so

This hadith teaches us the importance of respecting our brothers and their decisions. It is important to not interfere in any transactions or proposals that our brother has already made, unless they give us permission to do so. We must show respect for our brothers and their decisions, even if we disagree with them. This hadith also teaches us the importance of communication between siblings; it is important to talk to each other about any transactions or proposals that have been made before entering into them ourselves. By doing this, we can ensure that everyone involved is on the same page and no one’s feelings are hurt in the process.
