Silk in the Quran
18:31 Those, they shall live in the Gardens of Eden, underneath which rivers flow. They shall be adorned with bracelets of gold and arrayed in green garments of silk, and brocade, reclining therein on couches; how excellent is their reward and how fine is their resting place!
22:23 Allah will admit those who believe and do good works to gardens underneath which rivers flow. They shall be adorned therein with bracelets of gold and with pearls, and their garments shall be of silk.
35:33 They shall enter the Gardens of Eden, where they shall be adorned with bracelets of gold and with pearls, and there, their robes shall be of silk.
44:53 dressed in silks and brocade, set face to face.
76:12 and recompense them for their patience with a Garden, and robes of silk.
76:21 Upon them there will be garments of green silk, rich brocade, and they will be adorned with bracelets of silver. Their Lord will give them a pure beverage to drink.
Hadith - Sahih Al-Bukhari 7.693, Narrated Uqba bin Amir
A silken Farruj was presented to Allah's Apostle and he put it on and offered the prayer in it. When he finished the prayer, he took it off violently as if he disliked it and said, "This (garment) does not befit those who fear Allah!"
Hadith - Sunan of Abu Dawood #4037, Narrated Imran ibn Husayn
The Prophet (peace be upon him) said: I do not ride on purple, or wear a garment dyed with saffron*, or wear shirt hemmed with silk.
From al-Baraa’ ibn ‘Aazib (may Allah be pleased with him): “The Prophet (saaws) forbade us to use soft red mattresses and qasiy – garments with woven stripes of silk.” (Narrated by al-Bukhaari, 5390)
Her Marriage with the prophet was a Wahi (Divine Revelation). She, herself relates from the Prophet, ‘He said, "I saw you in dreams three times. The angel brought you to me and you were clad in white silk. He (the angel) said that it was your consort and he (angel) showed me by opening your face. You are just like that…" Sahih Muslim, Vol.2, p.285.
I am curious, if silk is going to be in heaven why would Muhammad have such a problem with it?
