Question:

Answer:
The width of two, three, or four fingers of silk is permissible for a man, such as a button, a small patch, and the like.
Q: And gold?
The Shaykh: No, gold is forbidden absolutely, whether a little or a lot.
Q: Who said it is permissible to use it for women only, gold and silver?
The Shaykh: The hadiths are general, my son; they encompass men and women.
Q: Regarding silk in war, is there anything reported about it?
The Shaykh: If there is a need for it, such as itching and the like, like what al-Zubayr wore, the Prophet (peace and blessings be upon him) granted a dispensation to al-Zubayr and 'Abd al-Rahman ibn 'Awf because of illness. Mere war is not sufficient; it does not make it permissible.
Q: Sitting on it and wearing the kanab?
The Shaykh: It is not permissible; this is not permissible.
Q: Not for women nor for men?
The Shaykh: It is not permissible for men to wear silk or sit on it, but women may wear silk.
Q: Using it for sitting?
The Shaykh: It is not suitable, because men come to the seating areas.
Q: So, is its use for women limited to clothing?
The Shaykh: The permission is specific to clothing, a shirt, trousers, nothing that contradicts this. As for carpets and seating areas, men and women come to them, so it is not suitable.
Q: Is it permissible for a woman to sit on silk?
The Shaykh: It is not permissible to use it as seating, because if she uses it, her husband will sit on it and her father will sit on it; it is a means for men to sit on it.
Q: What is dibaj?
The Shaykh: The thick kind of silk; the thick kind is called "dibaj," and the shiny kind is called "istabraq," the one that shines.
Q: We have another definition of dibaj, and we hope you will correct it if it is wrong. It says: with a kasrah on the dal and a sukun on the ya, followed by a ba: a garment whose warp and weft are silk.
The Shaykh: No, the known definition is this dibaj; it is the thick kind of silk.
