Fatwa: Ritual ablution after ghusl
--answered by Sayyid Allama Muhammad bin Abdul-Azeem al-Houthi
It is apparent that it is valid if one intended and performed the ritual ablution during the wash because he cleansed, rinsed the mouth and nose, washed the face and forearms, poured water on the whole body and washed the feet while intending to purify from major ritual impurity and the prayer.
The preference is that if time is restricted, there is no prohibition to suffice with the aforementioned method. However, if there is enough time, one should perform the ritual ablution.
