Read all Ahadith in the book of pilgrimage by sahih al muslim

Ibn 'Umar (Allah be pleased with them) reported that a person asked the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) what a Muhrim should put on as dress. Thereupon the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) said: Do not put on a shirt or a turban, or trousers or a cap, or leather stockings except one who does not find shoes; he may put on stockings but he should trim them below the ankles. And do not wear clothes to which saffron or wars is applied.

Salim reported on the authority of his father ('Abdullah b. 'Umar) that the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) was asked what a Muhrim should wear, whereupon he said: A Muhrim should not wear a shirt, or a turban, or a cap, or trousers, or a cloth touched with wars or with saffron, nor (should he wear) stockings, but in case he does not find shoes, but (before wearing stockings) be should trim them (in such a way) that these should become lower than the ankles.

Ibn 'Umar reported that the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) forbade the Muhrim to put on a cloth dyed in saffron or wars and he further said: One who does not find shoes (to wear) he may wear stockings, but (only) after trimming them below the ankles.

Ibn 'Abbas (Allah be pleased with both of them) reported: I heard Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) say as he was delivering an address: So far as the trousers are concerned, one who does not find lower garment, he may wear them; as also socks, he may wear them who does not find shoes. It concerns the Muhrim.

Amr b. Dinar narrated with the same chain of transmitters that he heard the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) delivering sermon at 'Arafat, and he made a mention of this hadith (as quoted above).

This hadith has been narrated on the authority of 'Amr b. Dinar with the same chain of transmitters, but none of them (the narrators) made a mention that he (the Holy Prophet) was delivering address at 'Arafat except Shu'ba.

Jabir (Allah be pleased with him) reported Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) as saying: He who does not find shoes to wear may wear socks, and he who does not find lower garment to wear may put on trousers.

Ya'la b. Umayya reported on the authority of his father (Allah be pleased with them) that a person came to the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) as he was at Ji'rana and he (the person) had been putting on a cloak which was perfumed, or he (the narrator) said: There was a trace of yellowness on it. He said (to the Holy Prophet): What do you command me to do during my Umra? (It was at this juncture) that the revelation came to the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) and he was covered with a cloth, and Ya'la said: Would that I see revelation coming to the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ). He (Hadrat 'Umar) said: Would it please you to see the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) receiving the revelations 'Umar lifted a corner of the cloth and I looked at him and he was emitting a sound of snorting. He (the narrator) said: I thought it was the sound of a camel. When he was relieved of this he said: Where is he who asked about Umra? When the person came, the Prophet ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) said: Wash out the trace of yellowness, or he said: the trace of perfume and put off the cloak and do in your 'Umra what you do in your Hajj.

Safwan b. Ya'la reported on the authority of his father (who said): A person came to the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) as he was staying at Ji'rana and I (the narrator's father) was at that time in the apostle's ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) company and (the person) was donning a cloak having the marks of perfume on it, and he said: I am in a state of Ihram for the sake of Umra, and it (this cloak) is upon me and I am perfumed. The Apostle of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) said to him: What would you do in your Hajj? He said: I would take off the clothes and would wash from me this perfume. Thereupon the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) said: What you do in your Hajj do it in your Umra.

Safwan b. Ya'la b. Umayya reported that Ya'la used to say to 'Umar b. Khattab (Allah be pleased with him): Would that I see revelation descending upon the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ). (Once) when the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) was in Ji'rana and there was a cloth which provided shade over him, and there were his Companions with him. 'Umar being one of them, there came a person with a cloak of wool on him daubed with perfume and he said: Messenger of Allah, what about the person who entered upon the state of Ihram with a cloak after daubing it with perfume? The Apostle of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) looked at him for a short while, and then became quiet, and revelation began descending upon him, and 'Umar gestured (with his hand) to Ya'la b. Umayya to come. Ya'la came and he entered his head (beneath the cloth and saw) the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) with his face red, and breathing heavily. Then he felt relieved (of that burden) and he said: Where is the man who was just asking me about Umra? The man was searched for and he was brought, and the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) said: So far as the perfume is concerned, wash it three times, and remove the cloak too (as it was sewn) and do in 'Umra as you do in Hajj.
