The narration about wudu, and why it is not here

You have been told to make wudu when you are angry. It is the single most repeated piece of advice in Muslim material on this subject, and you will meet it everywhere.

The report it comes from is Sunan Abi Dawud 4784. It says anger is from the devil, the devil was made of fire, fire is put out with water, and so an angry person should make ablution. Al-Albani graded it da'if, which means weak. This platform publishes only reports graded sound or good, so it is not being put in front of you as evidence.

We are saying that out loud rather than quietly leaving it out, because silence would just leave you wondering why it is missing. Cold water on your face may still settle you, and plenty of people find that it does. It is simply not being handed to you here as a prophetic instruction. The sound instructions on this are the ones above.

One more thing, because leaving it out would be arrogant. The scholars did carry this report. Ibn Qudamah lists wudu among the measures in Mukhtasar Minhaj al-Qasidin, in the same line that gives the three moves from the previous step and in the same order.

وأما العمل، فينبغي له السكون، والتعوذ، وتغيير الحال، وإن كان قائما جلس، وإن كان جالسا اضطجع، وقد أمرنا بالوضوء أيضا عند الغضب، فهذه الأمور وردت في الأحاديث.

Our rendering: as for action, he should have stillness, seeking refuge, and a change of state; if he was standing let him sit, and if sitting let him lie down; and we have been commanded to perform wudu at anger as well. These matters have come in the reports.

Ibn Rajab quotes the same chain in Jami' al-Ulum wa'l-Hikam. So the rule being applied on this page is a rule about what this platform publishes, which is only what is graded sound. It is not a verdict on their books.
