Ruling on performing some of the acts of the Day of Sacrifice before others

The second question in the letter of the brother: Abd al-Rahman Saleh Muhammad Ahmad from the Republic of Somalia. He says: Is there a sin on the pilgrim if he slaughters before he stones, or shaves before he slaughters? And is anything obligatory upon him, and what is the expiation? Please issue a ruling for us, may Allah reward you with good.
Answer: The Prophet (peace and blessings be upon him) on the Day of Sacrifice stoned the Jamarah in the forenoon, then he slaughtered his sacrificial animal (peace and blessings be upon him), then he shaved his head, then Aisha (may Allah be pleased with her) applied perfume to him, then he rode to the House and circumambulated it. This is the Sunnah (recommended practice), and he said: May Allah send blessings upon him and grant him peace. This is what is required of the pilgrim, and this is the best: that he stones, whether he is a man or a woman, first the Jamarat al-Aqabah on the Day of Sacrifice with seven pebbles, then he slaughters his sacrificial animal if he has one, then after that he shaves his head or shortens his hair, and with this the first state of release is achieved. So he wears sewn clothes and applies perfume as the Prophet (peace and blessings be upon him) did, then the circumambulation comes after that. And he is not permitted to approach women until he circumambulates and performs the Sa'y (walking between al-Safa and al-Marwah) if he has a Sa'y remaining after the stoning and shaving. As for if he stoned and shaved, he applies perfume, wears sewn clothes, covers his head, trims his nails, and trims his mustache, and there is no harm in that. But he does not approach the woman until he adds to the stoning and shaving the circumambulation and the Sa'y if he has a Sa'y remaining. But if he performs some of them before others, there is no harm. If he shaves before he stoned, or slaughtered before he stoned, or circumambulated before he stoned, or circumambulated before he slaughtered, there is no harm in that. Or if he performed the Sa'y before the circumambulation as some ignorant people do, it is established from him (peace and blessings be upon him): And a man said to him: (peace and blessings be upon him).
This is from the gentleness of Allah and His mercy and His kindness to His servants (Exalted and Majestic is He). So it is prescribed for the pilgrim, whether male or female, to do what the Messenger (peace and blessings be upon him) did: that he stones first on the Day of Sacrifice, then slaughters his sacrificial animal if there is one, then shaves or shortens, and shaving is better, then circumambulates and performs the Sa'y if he has a Sa'y remaining. This is what is prescribed. So if he performs some of them before others and does not arrange them in order, there is no harm on him, as mentioned before. If he shaves before he stoned, or circumambulated before he stoned, or slaughtered before he stoned, or shaved before he slaughtered, or circumambulated before he slaughtered, all of it is without harm. And likewise, if he performs the Sa'y before the circumambulation, according to the correct opinion, even though it is contrary to the opinion of the majority, but it is the correct one; because the text came with it from the Prophet (peace and blessings be upon him). So if one performs the Sa'y before the circumambulation while ignorant or forgetful, there is no harm on him, and his Sa'y is valid. Yes.
