Abu Uthman Hindi says: A letter came to us from Sayyiduna Umar (may Allah be pleased with him); we were with Sayyiduna Utbah bin Farqad (may Allah be pleased with him) in Azerbaijan or Syria. In that letter, it was written: "As for what follows! The Noble Prophet (peace and blessings be upon him) forbade wearing silk, except for the width of two fingers." Abu Uthman says: We understood that (by two fingers it means) that stripes or marks of silk of that width are permissible.

(Second chain) Abu Uthman Nahdi says: We were with Sayyiduna Utbah bin Farqad (may Allah be pleased with him), when Sayyiduna Umar (may Allah be pleased with him) sent him some written instructions, which he had narrated from the Noble Prophet (peace and blessings be upon him). In it, it was also written that the Noble Prophet (peace and blessings be upon him) said: Only that person wears silk in this world who has no share in the Hereafter, except equal to two fingers. Along with this, the Prophet (peace and blessings be upon him) gestured with his index and middle fingers. Abu Uthman says: When we saw the Tayalisi garment, we estimated that the buttons of the Tayalisi garment were of this amount.

(Third chain) Abu Uthman says: We received a letter from Sayyiduna Umar (may Allah be pleased with him) while we were in Azerbaijan. It was written in it: O Utbah bin Farqad! Beware of luxury, adopting the appearance of the polytheists, and wearing silk garments, because the Noble Prophet (peace and blessings be upon him) forbade us from wearing silk, except for this much—at the same time, he (peace and blessings be upon him) raised his two fingers to clarify.

Suwaid bin Ghaflah says: Sayyiduna Umar bin Khattab (may Allah be pleased with him) delivered a sermon at the place of Jabiya and said: The Noble Prophet (peace and blessings be upon him) forbade wearing silk, except for an amount equal to two or three or four fingers, and at the same time, he (peace and blessings be upon him) gestured with his palm.

Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that the Noble Prophet (peace and blessings be upon him) forbade that garment which is made entirely of silk. If the warp of the cloth is of silk or the embroidery is of silk, then we do not consider there to be any harm in it.

It is narrated from Sayyida Asma bint Abi Bakr (may Allah be pleased with them both) by her freed slave Abdullah, who says: Sayyida Asma (may Allah be pleased with her) sent me to Sayyiduna Ibn Umar (may Allah be pleased with them both) to ask him about this matter: Has it reached you from Sayyida Asma (may Allah be pleased with her) that you declare three things forbidden: putting marks and designs on clothes, red silk cushions, and fasting all the days of Rajab? He replied: As for what you said that I do not fast all the days of the month of Rajab, then how would it be for the one who always fasts? As for what you mentioned about marks on clothes, that I prohibit it, I heard Sayyiduna Umar (may Allah be pleased with him) say that the Noble Prophet (peace and blessings be upon him) said: Whoever wears silk in this world will not wear it in the Hereafter.

Abdullah narrates that I went to Lady Asma (may Allah be pleased with her), and she brought out a Tayalisi cloak, which had a piece of Persian silk attached to its hem, and its slits were also of silk. She said, "This was the cloak of the Prophet Muhammad (peace and blessings be upon him), which he used to wear. It was with Lady Aisha (may Allah be pleased with her), and when she passed away, I took it. We soak it in water for a sick person and seek healing through its blessing."

Abdullah narrates that Sayyida Asma (may Allah be pleased with her) placed a cloak before us, which had silk buttons. She said: This is the cloak in which the Noble Prophet (peace and blessings be upon him) used to meet the enemy, (that is, he wore it in both times of peace and war).
