Can marriage be solemnized under the current circumstances that prevent official marriage contracts due to the coronavirus pandemic, by writing a document, having it witnessed, and announcing it via social media to avoid incurring God's wrath?

For a Muslim woman's marriage to be valid, a guardian (wali) is required. This guardian must be of her religion, and the order of guardianship is: her father, then her paternal grandfather, then her brother, then her brother's son, then her paternal uncle, then her paternal uncle's son. If she has no Muslim guardian, the judge (qadi) will act as her guardian. If no judge is available, a just Muslim man, such as the imam of the mosque, may act as her guardian. If that is not possible, guardianship transfers to the most suitable available person, such as the leader of a caravan or the head of the village. If it is not possible to go to court, then the imam of the mosque, one of the scholars, or a just Muslim man may solemnize her marriage, provided there are two Muslim witnesses, and the marriage is later documented.
