Narrated 'Abdur-Rahman bin Al-Qasim:
I heard my father who was the best man of his age, saying, "I heard 'Aisha (radiallaahu `anhaa) saying, 'I perfumed Allah's Apostle (sallallaahu `alayhi wasallam) with my own hands before finishing his Ihram while yet he has not performed Tawaf-al-Ifada.' She spread her hands (while saying so.)"
It is not permissible for the pilgrim in ihraam, man or woman, to put on perfume after entering ihraam, because the Prophet (peace and blessings of Allaah be upon him) said: “And do not wear any garment that has been touched by saffron or safflower.” And ‘Aa’ishah (may Allaah be pleased with her) said: I put perfume on the Messenger of Allaah (peace and blessings of Allaah be upon him) for his ihraam before he entered ihraam, and when he exited ihraam before he circumambulated the Ka’bah. Agreed upon. And the Prophet (peace and blessings of Allaah be upon him) said concerning a man who died when in ihraam: “Do not put any perfume on him.” Saheeh – agreed upon.
Firstly: the actions of the Day of Sacrifice are three for the pilgrim who is doing Ifraad. They are: stoning Jamrat al-‘Aqabah, shaving the head or cutting the hair, and tawaaf al-ifaadah, plus saa’i if he did not do it after the tawaaf of arrival. For those who are doing Tamattu’ or Qiraan, they must also slaughter the sacrifice. The one who is doing tamattu’ must also do saa’i after tawaaf al-ifaadah.
Secondly: these actions should be done in the following order: stoning the Jamrah, then offering the sacrifice, then shaving the head or cutting the hair, then tawaaf and saa’i. This is best, following the example of the Prophet (peace and blessings of Allaah be upon him), because he stoned the Jamrah, then offered the sacrifice, then shaved his head, then ‘Aa’ishah put perfume on him, then he went to the Ka’bah (to do tawaaf al-ifaadah). He was asked about the order in which these actions were to be done, by those who had done some of them ahead of others, and he said: “It doesn’t matter, it doesn’t matter.”
Thirdly: Whoever does two of them apart from offering the sacrifice has thus completed the first stage of exiting ihraam, hence it becomes permissible for him to do all the things that were forbidden to him whilst in ihraam, apart from intercourse. When he has done all three, then everything that was forbidden to him become permissible, including intercourse. There are many ahaadeeth concerning this which point to this meaning.
