Making Wudu after Ghusl
The Question
Do we have to do wudu after doing ghusl?
The Answer
No we don't have to make wudu after ghusl. This is because wudu and ghusl are two acts of worship of the same type, so the smaller act can be made part of the bigger act. This is similar to Umrah and Hajj, two acts of worship of the same type, so Umrah can be made part of Hajj. Yes, you can make wudu with ghusl, but then wudu should be before ghusl, not after. This was the Sunnah of the Prophet.
The Question
Ghusl will suffice for wudu only if it includes all
the obligatory parts of wudu. Isn't it?
The Answer
Ghusl does include all parts of Wudu. In fact, the bear minimum of Ghusl is to wash the WHOLE outer body with water along with Madmadah (rinsing the mouth) and Istinshaaq (breathing water in and out) - the inside of mouth and nose are considered from the outer body. Any Ghusl that falls short from that is not valid.
