Sometimes اشهد ان 'ašhadu 'an = "I witness that" is prefixed to each half of the Shahadah.

Sometimes و wa = "and" is prefixed to the first word of the second half of the Shahada.

Some Indonesian Muslims pray "Allah il Allah" when appealing for God's help. This is an altered form of the first part of the Shahadah.

Some Shia Muslims add "and Ali is the beloved of Allah" (wa-Aliyun waliyu 'llah) at the end. Some Shias don't believe that this is obligatory, however, and that the standard Shahadah (There is no god but Allah and Muhammad is His Messenger) is enough.
