Answered by Shaykh Faraz Rabbani
Can ghusl be considered wudu for prayer? If I did ghusl and then immediately pray without doing a separate wudu, is that okay?
Ghusl is major purity, and it ‘contains’ the minor purity of wudu. As such, when you do ghusl, you are on wudu, too.
And Allah alone gives success.
