What is the ruling on performing sa'y (walking between al-Safa and al-Marwah) before tawaf (circumambulation of the Ka'bah)?

Question : If a person performing 'Umrah (the lesser pilgrimage) performs sa'y (walking between al-Safa and al-Marwah) before performing tawaf (circumambulation of the Ka'bah), and then performs tawaf afterwards, does he have to repeat the 'Umrah from the beginning?

Answer : If a person performing 'Umrah performs sa'y before tawaf and then performs tawaf, he does not have to repeat anything except the sa'y. This is because the order between tawaf and sa'y is obligatory.
The Messenger of Allah (peace and blessings be upon him) rode between them and said, "Learn from me your rituals." If we learn his rituals from him, what do we start with? We start with tawaf first, then sa'y second. How can you say otherwise?
It is authentically reported from the Prophet (peace and blessings be upon him) that he was asked: You say he must repeat the sa'y, but the hadith says there is no harm. The answer to this is that the hadith was reported regarding Hajj (the major pilgrimage), and the difference here is between 'Umrah and Hajj.
'Umrah consists of two acts, not three, and there is no fourth act. They are tawaf, sa'y, and shaving the head. As for the preceding ihram (the consecrated state of pilgrimage), it is... yes... for entering into it.
If the order between tawaf and sa'y is disrupted, the defect in it is major. As for the order between sa'y and tawaf in Hajj, if it is disrupted, the defect in the Hajj is not major due to the multitude of its pillars and acts. This is what appears to me in this issue. Some of the Tabi'un (the generation after the Companions) and some scholars held that if a person performs sa'y before tawaf in Hajj or 'Umrah while forgetting or being ignorant, he owes nothing. If he does it intentionally, it is not permissible, because playing with... in shaving... with his permission...
There is, our professor, the hadith of 'Abdullah ibn 'Amr, narrated by Abu Dawud with a valid chain. He was in a hurry. Meaning... I performed sa'y before I performed tawaf.
For this reason, some scholars who do not see the permissibility of performing sa'y before tawaf in Hajj interpreted it as meaning that this man was a qarin (combining 'Umrah and Hajj in one ihram) and performed sa'y before performing tawaf al-ifadah (the circumambulation of farewell). This is actually a very weak position, because if a qarin performs sa'y before tawaf al-ifadah, does he need to ask or not?
The research is not about the qarin in Hajj. If a qarin performs sa'y before tawaf al-ifadah, he does not need to ask, because the Messenger of Allah (peace and blessings be upon him) performed sa'y while he was a qarin before performing tawaf al-ifadah, so he does not need to ask. The apparent action of the man is that he performed sa'y on the day of 'Id (the festival) itself, performing sa'y before tawaf. Yes.
