Answered by Shaykh Ilyas Patel
There are many ahadith which permit the wearing of red by men. The ahadith on the wearing of red by men are more authentic in chains of transmitters, than the ahadith of prohibition, except clothes, which are dyed with saffron.
Bara’a reports that, “The Prophet (Allah bless him and give him peace) was of medium build. I saw him once in a red garment and have never seen anything beautiful than him.” (Bukhari)
Abu Hujayfa reported similarly, saying, “Isaw the Prophet (Allah bless him and give him peace) in a red garment.”
Abu Dawud related from Hilal ibn Aamir from his father, “I saw the Prophet (Allah bless him and give him peace) giving a sermon on a camel in Mina, and he had on him a red garment.”
Imam Zafar Ahmad Usmani quotes Durr al-Muhtar with Hashiya ibn Abidin:
“There is no problem in all the colours for men, except those dyed with saffron.
It is mentioned in Mujtaba, Quhastani, and Sharh Niqaya of Abu Makarim as follows: There is no problem in wearing red clothes. This indicates that the (karaha) offensivness is slight (tanzihi)…
Allama Ibn Abidin says (wearing red clothes) has been narrated by Imam Abu Hanifa, as mentioned in Multaqat. And it shows that the karaha (offensiveness) is tanzihi, because the word ‘la ba’s’ is used generally in leaving things, which is better.” [I’la al-Sunan, Zafar Ahmad Usmani, 17.358-360)]
