What is the most accurate pronunciation of the word *Sattir* in the hadith: “Indeed, Allah is the Most Modest, the Most Concealer,” with a kasrah on the *sin* or a fathah?

The questioner : The hadith of *Sattir* or *Sattir* with a fathah on the *sin* or a kasrah on the *sin*?

The Shaykh : By Allah—may Allah reward you with good—I did not speak knowing whether you were with me or with someone else that it was necessary to check, and perhaps you have it? And, it escaped my memory; we have not checked it yet, so perhaps we will check it, if Allah wills.

The questioner : It is fixed in al-Bukhari from Musa (peace be upon him) as *Hayy Sattir* with a kasrah on the *sin*. Ibn Hajar says the most correct form in the language is the *fa'il* form on the pattern of *Rahim*. He said: It is permissible to say *Sittir* on the pattern of *fi'il*...

The Shaykh : Yes, this means there are two opinions and two perspectives in the issue. I do not have a reference at the moment, but what is in my mind and on my tongue is *Sittir*. So, the transmission of the brother here, Abu Hamzah, indicates that this has a basis.
Yes, that is correct. Anything else?

The questioner : Do you have a comment, our Shaykh...?

The Shaykh : No, I have no comment until it is established that the opposite is the case; because this... is Muslim.
Yes.
