Sunni and Shia are both fundamental practices in the Islamic faith, both united in many of their beliefs; however, there is a clear divide that began centuries ago regarding who should succeed Prophet Muhammad as a leader of the Islamic.
Sunni Muslims believe that it was the right decision to have someone who was most capable of doing the job, while Shia Muslims believe that the successor should have come from within the family of the late Muhammad. Sunnism is the leading and most orthodox branch of Islam.
Now, concerning Nikah, Shia Muslims believe in Mutah or marrying a woman for a brief time while Sunni Muslims do not believe in this ritual, which has been forbidden by the prophet. There are also differences in their religious practices, but only by a small measure.
Shia Nikah and Sunni Nikah are the two main subgroups of Islam, and they have different religious beliefs and practices. Nikah is a marriage pact between a Muslim man and a woman. Both Sunni and Shia brides are supposed to sign the marriage certificate or Nikah Nama.
In the Sunni Nikah ceremony, it is mandatory to have two adult male witnesses, and they do not have this rule at the time of divorce. On the other hand, Shias do not require two witnesses present at the wedding ceremony; however, it is necessary at the time of separation.
Shias also believe in temporary marriage, while Sunnis do not approve of such a thing. A Shira Nikah ceremony is longer than a Sunni Nikah ceremony. There are also differences in traditional and ritual practices between the two at the time of the Nikah ceremony. Sunni and Shia devotees do not condone marrying outside religions.
