What is the ruling regarding the validity of the 'umrah of one who performed sa'i between Safa and Marwah three times at Safa and four times at Marwah due to ignorance?

The Sa'i (ritual circumambulation between Safa and Marwah) is invalid, and consequently, the 'Umrah is invalid. This is due to not starting at Safa during the Sa'i and not completing all seven circuits. This is the opinion of the majority of scholars, based on the Prophet Muhammad's (peace be upon him) saying: "We begin with what Allah began with," and Allah's Almighty saying: "Indeed, As-Safa and Al-Marwah are among the symbols of Allah." [Quran 2:158], as Safa is mentioned first. However, it is well-known from Abu Hanifa that the order is not a condition.
