If one reads part of al-Fatihah while beginning to stand up, is his prayer valid?

The questioner : We are in our fourth year. He reads part of al-Fatihah during the standing.

The Shaykh : And he was able to.

The questioner : What is the conclusion?

The Shaykh : This is not correct. If he reads a letter of it while sitting, it is not valid.

The questioner : Oh, save us. Yes. After I did the prostration, then...

The Shaykh : After he rises from the prostration.

The questioner : In the name of Allah, the Most Gracious, the Most Merciful.

The Shaykh : Yes, the recitation of al-Fatihah is not valid. The recitation of al-Fatihah is not valid. And know that in rising there is only the takbir, there is only the takbir. Say the takbir, and if it happens that you finish the takbir before you are fully standing, there is no dhikr in it.
