Some have argued that Lord Shiva is not Allah. Christians believe that Jesus is the true God. The god of Hinduism is Satan, all the gods in Hinduism are man-made gods. Similarly, Muslims ignore the fact that Allah is the true God, the God of Hinduism or Shiva is not Allah.

There is also no concept of original sin in Islam. Islam has no concept of original sin, need for atonement, or ecclesiastical confession. Another contrast to Christianity is, that sin isn't seen as the worst. Abu Uthman al-Maghribi argues that sin is better than complacency, since the sinner makes tawba.

Allah, the one and only God in Islam. Etymologically, the name Allah is probably a contraction of the Arabic al-Ilāh, “the God.” The name's origin can be traced to the earliest Semitic writings in which the word for god was il, el, or eloah, the latter two used in the Hebrew Bible (Old Testament).

The Prophet (peace_be_upon_him) said: Allah will raise for this community at the end of every hundred years the one who will renovate its religion for it.
