There is a girl that I really want to have intercourse with. However, I don’t think we are at the stage to marry permanently. Is there a way temporary marriage can be done in a halal way?
Temporary marriage or Nikah Mut'ah (literally translating to 'pleasure marriage') is forbidden:
"Ali said to Ibn'Abbas, may Allah be please with them both: The Prophet forbade Mut'ah marriage, and the flesh of domesticated donkeys on the Day of Khaibar."' (Sahih, Sunan an-Nasa'i)
Sunni Islam forbids temporary marriages for pleasure, so you should either marry a person for good with the intention of a full marriage or fast to supress your desires.
Likewise Zaidi Shias, Ismaili Shias, and Dawoodi Bohras all consider it forbidden because Ali (RA) reported the Prophet (SAW) forbidding it.
On the other hand, Twelver Shia consider Nikah Mut'ah permissible, because they do not accept the above hadith, and they use the verse 4:24.
All in all, Sunnis are in agreement that it is forbidden and Shias are divided on the matter.
