You stated that the two witnesses are a condition for the validity of the marriage contract. If a man contracted a marriage without witnesses because he considered the hadith weak, and then it became clear to him that the hadith is authentic, does he renew the contract?

The questioner : You have mentioned that the two witnesses are a condition for the validity of the marriage contract. If a man contracted a marriage without witnesses based on his view that the hadith was weak, and then it became clear to him after the contract that the hadith is authentic, does he renew the contract?

The Shaykh : No, this is like the marriages of the disbelievers that Islam recognized. It is even more fitting that it be recognized and established by the Shari'ah. However, if he contracts a new marriage, it is not valid except with two witnesses. If he marries anew and contracts with a new wife, it is not valid except with two just witnesses.
