`Sayyiduna Ibn Umar (may Allah be pleased with them both) narrates that Sayyiduna Umar (may Allah be pleased with him) saw ‘Atard al-Taymi in the market with a silk garment (for sale), and he was a person who used to go to kings and receive money from them. Sayyiduna Umar (may Allah be pleased with him) submitted to the Messenger of Allah (peace and blessings be upon him): O Messenger of Allah! I saw ‘Atard with a silk garment in the market; if you buy it and wear it when the Arab delegations come, it would be appropriate. The narrator said: I think he also said that you could wear it on Fridays as well. The Messenger of Allah (peace and blessings be upon him) said: Only he will wear silk in this world who has no share in the Hereafter. Then, after that, some silk garments came to the Messenger of Allah (peace and blessings be upon him), so he gave one garment each to Sayyiduna Umar, Usama bin Zayd, and Ali (may Allah be pleased with them all), and said: Tear it and make headscarves for your women. Sayyiduna Umar (may Allah be pleased with him) brought his garment and said: O Messenger of Allah! You sent this garment to me, and just yesterday you said what you said about ‘Atard’s garment? The Messenger of Allah (peace and blessings be upon him) said: I did not send this garment to you for your own wearing, but so that you may benefit from it (by selling it). And Sayyiduna Usama (may Allah be pleased with him) wore his garment and went out, so the Messenger of Allah (peace and blessings be upon him) looked at him in such a way that he realized the Messenger of Allah (peace and blessings be upon him) was displeased. He said: O Messenger of Allah! Why do you look at me? You are the one who sent this garment to me. The Messenger of Allah (peace and blessings be upon him) said: I did not send it to you so that you wear it yourself, but so that you tear it and make headscarves for your women.

Khalifah bin Ka'b Abu Dharr reports: I heard Abdullah bin Zubair (may Allah be pleased with him) while he was delivering a sermon, saying: O people, beware! Do not clothe your women in silk garments, for I heard Umar (may Allah be pleased with him) say: I heard the Messenger of Allah (peace and blessings be upon him) say: Do not wear silk, for whoever wears it in this world will not wear it in the Hereafter.

It is narrated from Sayyiduna Uqbah bin Amir (may Allah be pleased with him) that he said: A silk cloak was presented as a gift to the Messenger of Allah (peace and blessings be upon him), so he wore it and performed prayer in it. After finishing the prayer, he took it off forcefully, as if he disliked it, and then said: "This is not suitable for the pious."

Abu Uthman says that Syedna Umar (may Allah be pleased with him) wrote to us while we were in Azerbaijan (a country in Iran): "O Utbah bin Farqad, the wealth that is with you is neither earned by you, nor by your father, nor by your mother. So let the Muslims enjoy it in their places just as you enjoy it in your place (i.e., deliver it to them without them asking). And avoid living luxuriously, and avoid the ways of the polytheists, and also avoid wearing silk clothes—except this much." And the Messenger of Allah (peace and blessings be upon him) raised his middle and index fingers and joined them together (i.e., if there is a border of two fingers' width, it is permissible). Zuhair said to Asim, "This is what is in the book," and Zuhair raised both his fingers.

It is narrated from Suwaid bin Ghaflah that when Sayyiduna Umar bin Khattab (may Allah be pleased with him) delivered a sermon at (the place of) Jabiyah, he said that the Messenger of Allah (peace and blessings of Allah be upon him) forbade wearing silk (silken cloth), except (that) it be equal to two fingers, or three, or four fingers (in width).

Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) once wore a silk cloak which had been gifted to him. Then he immediately took it off and sent it to Sayyiduna Umar (may Allah be pleased with him). The people said, "O Messenger of Allah! You have taken it off?" The Prophet (peace and blessings be upon him) replied, "Jibreel has forbidden me." Upon hearing this, Sayyiduna Umar (may Allah be pleased with him) came to the Prophet (peace and blessings be upon him) weeping and said, "O Messenger of Allah! You gave me something which you disliked; what will become of me?" The Prophet (peace and blessings be upon him) said, "I did not give it to you to wear, but rather so that you may sell it." Then Sayyiduna Umar (may Allah be pleased with him) sold it for two thousand dirhams.

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) permitted Sayyiduna Abdur Rahman bin Awf and Sayyiduna Zubair bin Al-Awwam (may Allah be pleased with them both) to wear silk shirts during a journey, because they had developed itching or some other illness. In another narration, it is mentioned that both of them had complained of lice.

It is narrated from Abdullah, who was the freed slave of Asma bint Abi Bakr (may Allah be pleased with them both) and the maternal uncle of the son of Ata, that he said: Asma (may Allah be pleased with her) sent me to Abdullah ibn Umar (may Allah be pleased with them both) and told me to say: I have heard that you declare three things to be forbidden: one is a garment with silk embroidery, the second is an argwan (i.e., a bright red) saddlecloth, and the third is fasting for the entire month of Rajab. So Abdullah ibn Umar (may Allah be pleased with them both) said: Who says that fasting in the month of Rajab is forbidden? Whoever fasts continuously (Abdullah ibn Umar (may Allah be pleased with them both) used to fast continuously except on the two Eids and the days of Tashreeq, and his opinion was that perpetual fasting is not disliked). And as for what you mentioned about garments with silk embroidery, I heard Umar (may Allah be pleased with him) say: I heard the Messenger of Allah (peace and blessings be upon him) say: "Silk will be worn by the one who has no share in the Hereafter." So I feared that embroidered garments might also be silk. And as for the argwan saddlecloth, Abdullah's own saddlecloth is argwan. I conveyed all this to Lady Asma (may Allah be pleased with her), and she said: The cloak of the Messenger of Allah (peace and blessings be upon him) is present here. Then she brought out a Tayalisi Kisrawani cloak (which was attributed to the Persian king Kisra), which had silk on its collar and its hem was also of silk. Lady Asma (may Allah be pleased with her) said: This cloak remained with Umm al-Mu'mineen Aisha Siddiqa (may Allah be pleased with her) until she passed away. When she died, I took this cloak, and the Messenger of Allah (peace and blessings be upon him) used to wear it. Now we wash it and give its water to the sick for healing. (A silk border up to four fingers' width on the hem is permissible; more than that is forbidden.)

It is narrated from Amir al-Mu'minin, the rightly guided Caliph, Sayyiduna Ali ibn Abi Talib (may Allah be pleased with him) that the king of Duma, Ukaydir, sent a gift of a silk garment to the Messenger of Allah (peace and blessings be upon him). The Prophet (peace and blessings be upon him) gave it to me and said: Tear it and make headscarves for the three Fatimas (one for Sayyida Fatima [may Allah be pleased with her] , one for Fatima bint Asad, the mother of Sayyiduna Ali [may Allah be pleased with him] , and one for Fatima bint Hamza [may Allah be pleased with her] ).

It is narrated from Amir al-Mu'minin Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) forbade wearing Qassi (a type of silk cloth), wearing clothes dyed with Kusum, wearing a gold ring, and reciting the Qur'an during bowing (ruku‘).
