Shama-il Tirmidhi Chapter 8, Hadith Number 9 (61).

Abu Juhayfah (R.A) says, “I saw Rasulullah (S.A.W) wearing a pair of red (coloured) clothing. The lustre of the feet of Rasulullah (S.A.W) is still before me.” Sufyaan (R.A) who is a narrator of this hadith says: “According to my understanding the pair (of clothing) was printed red.”

Commentary.
This incident took place at the time of Hajjatul-Widaa, as is stated if the Bukhaari and other kitaabs of hadith. Sayyidina Sufyaan (R.A) ‘Anhu’s reason for saying that this was a red coloured clothing (for men). There is a difference of opinion among the ‘Ulama’. The Hanafis also state a number of opinions. This has been discussed in the first chapter. Before choosing red-coloured clothing an ‘aalim should be consulted. Maulana Gangohi has mentioned a few times in his fataawa (religious rulings) that it is permissible for a man to wear red patterned garment’s. From the point of taqwaa (piety) it is better for a man not to wear red coloured garments, since there is a difference of opinion among the learned ‘Ulama’.
