The ruling on touching the perfume attached to the Black Stone during tawaf

Question : The Black Stone is covered with perfume. Is it prescribed to touch it while in the state of ihram and during tawaf around the House?

Answer : According to the principles of the jurists, if this perfume sticks to the hand, you should not touch it. Do not touch it, because if you touch it, you are required to remove it immediately, and this is difficult to do during tawaf.
However, it is narrated from some of the Salaf, such as 'Ata, that he saw no harm in the perfume of the Ka'bah that a person in ihram comes into contact with. It appears that he (may Allah have mercy on him) held that it is difficult to avoid this.
If this issue is authentic from 'Ata, and as is well known he was from the Tabi'un, it is also necessary to look into whether it is authentic from the Companions (may Allah be pleased with them). If this statement is authentic, it is a sound opinion because it is difficult to guard against it. Otherwise, the principles of the jurists require that if you see perfume on it that sticks to the hand, you should not touch it.
