Is a marriage contract valid if concluded in jest or under duress?

Primary text

A marriage contract concluded in jest (hazl) or under duress (talji'ah) is valid. This is established by the statement of the Prophet, peace be upon him: "Three things, their jest is serious, and their seriousness is serious: divorce, marriage, and revocation (ruj'a)." This hadith is narrated by Al-Tirmidhi. Furthermore, the Prophet, peace be upon him, stated: "Whoever marries while playing, or divorces while playing, or frees a slave while playing, it takes effect." Evidence is also found in the statements attributed to the Companions regarding matters whose seriousness holds true even when uttered playfully.
