Show mercy and kindness towards each other

In this hadith, the Prophet Muhammad is warning his followers against disbelief and violence. He says "wailakum" or "waihakum", which can be translated as either "woe to you" or "may Allah be merciful to you". He then goes on to say that they should not become disbelievers after him by cutting the necks of one another. This hadith teaches us that we should not turn away from our faith in God, nor should we resort to violence when dealing with others. We must show mercy and kindness towards each other, even if we disagree on certain matters. This hadith also serves as a reminder that it is important for us to stay true to our beliefs and values, no matter what challenges come our way.
