Abominable (Makruh things in ihram or matters disliked in Shariah) however no atonement or penalty is necessary to compensate
(1) Removing by rubbing the dirt from the body.
(2) Washing the hair or body with soap etc. is an abominable act, because  there is a narration of hadith by Hadrat abdullah Bin Umar radiallaahuta’la anhuma saying that somebody asked, “YaRasoolullahsallallahuta’laalaihiwasallam !  how the Haji should remain ?”  He ,sallallahualaihiwasallam said. “With lose hair and dirty.”
(Sharah us-sunnah lilBaghvi, Book of Haj, Part of wujub ul-Haj, Hadith: 1840, Volume 4, Page 9)
(3) Combing the hair on the head or of the beard.
(4) Scratching the head in such a way that the hair may go broken and fall or the lice would fall off.
(5) Deliberately smelling the scent.
(6) Smelling the aromatic fruits or leaves, such as lemon, mint leaves, orange. (Eating is not prohibited).
(7) Visiting or sitting in the market or shop of scents with the intention to feel the smell.
(8) Touching any fragrance or perfume without applying the same on the hand. If that fragrance is applied on the hand then it becomes haraam.
(9) Consuming any eatable or soft drink which is splashed with aroma after that has been cooked or prepared, is also an abominable act. Yes, but anything aromatic added in the food or drink before their preparation, and the aroma has disappeared, then there is no objection in their consumption.
(10) If the perfume is not applied on the Ghilaf (cover) of kaba but entering into the ka’bah in such a way that the ghilaf may rub against the head or face, then this act is also becomes abominable. But keep in mind that generally perfume has always been applied on the Ghilaf of Kaba, hence restraining is reasonable. However, by touching the Ghilaf of Kaba and rubbing the hands on the face and by clinging the full body with the ghilaf with the intense affection and love there is a possibility of getting the perfume stuck on the ihram. In ihram such act becomes haraam where atonement or penalty applies. Hence avoiding such acts is better.
Note: Wherever the issue of perfume comes find out from others their opinion regarding the intensity of smell. Since the penalty applies on theamount of the perfume stuck, our own self may misjudge the intensity of the perfume to the lesser side.
(11) Wearing the cloth that was not stitched but roughed up with thread (or repaired by thread) or wearing cloth with patches is also abominable.
(12) Sleepingface down on the pillow is abominable. So, while travelling in the bus, avoid keeping the face at the back of the front seat for sleeping.
(Without ihram too, It is forbidden to sleep on the belly, and it has been told in the holy hadith that this is the practice of denizens of hell)
(13) Tying on the arm any talisman wrapped in an unstitched cloth is abominable. If the talisman wrapped in an unstitched cloth but not tied with the arm and worn around the neck, then there is no objection.
(14) Without any excuse, tying a bandage on any part of the body.
(15) Beautifying and putting up make-up.
(16) Putting knots at the edges of the ihram coverlets.
(17) It is admissible to use belt to preserve the cash, passport etc. Hence, only with this intention one may tie the belt around the waist, which also useful to secure the ihram coverlet. However, using the belt or rope only with the intention of securing the coverlet around the waist is abominable.
(18) Hiding the nose or any part of the face is abominable. (Hence, avoid cleaning the nose with handkerchief for flu).
(19) If the nose or any part of the face is hidden in such a way that the cloth does not touch, then too it is abominable. If the cloth touches the face, then it become haraam.
