Question:
Is it wrong to use the word betrothal or khitba or engaged (which is the waiting time before the wedding)? It is wrong to say that I'm bride? If wrong or right, send me the sources please
about betrothal. Thank you so much

Answer:
It is permissible in Islamic law (shari'ah) to use all of these terms. Evidence from primary texts are as follows:

In the Quran God the Almighty says, "There is no blame upon you for that to which you [indirectly] allude concerning a proposal to women." (Qur'an 2:235)

As for evidence from the Sunnah, Imams Bukhari and Muslim reported that Al-Misswar Ibn Makhrammah (may God be pleased with him) narrated, "Ali betrothed (khataba) the daughter of Abu Jahl." By the end of the hadith, he said, "Ali broke up the betrothal."

Likewise, in his copious Sahih, Bukhari dedicated a chapter to this issue titled, "Chapter on explaining the reasons for breaking a betrothal up". He also made another chapter in his book titled, "Impermissibility to betroth an already betrothed woman unless her fiancé allows it or break up the betrothal".

Imam Muslim also titled a chapter in his Sahih, "Chapter on Prohibition of betrothing the fiancée of one's brother unless he allows it or break up the betrothal".

It was reported that Sahl Ibn Sa'd said, "Abu Usayyd al-Sa'ddi invited the Messenger of God (peace and blessings be upon him) to his wedding ceremony, while Abu Usayyd's bride was serving the guests on the day of her wedding."
