Is the contract valid with one witness present, despite the large number of attendees at the time of its writing?

The majority of scholars hold that the stipulation of two righteous witnesses is among the conditions for marriage, while Malik is of the opinion that the only condition is public announcement. If, at the time of the عقد (marriage contract), there was only one witness accompanied by a group of people, many scholars deem the marriage valid. It has also been narrated from Ahmad that he said marriage is valid with the testimony of women if a man is with them.
