Some examples:
God:
Shia: Inconceivable by imagination and eyesight. Is not physical and has no physical attributes. Has nothing in common with His creations.
Sunni: Can be seen by the eyes and has human-like forms and attributes.
Prophets (specially Muhammad peace be upon him) :
Shia: Are infallible and free from sin. Are at the pinnacle of morals and ethics. They are bestowed with God given knowledge that encompasses everything.
Sunni: Prophets make mistakes and go about cursing and swearing to the faithful. Their knowledge is limited and they are like normal people in worldly affairs and can be ignorant in this scope.
The successor to the Prophet:
Shia: Can only be selected by God for He is the only person that knows who is best suited for this task. The successor to the Prophet must necessarily be free from sin and infallible and must have God given knowledge to prevent him from misguiding the people. The successors are twelve people called the Imams.
Sunni: The successor of a Prophet is chosen by the people. Is not infallible and can be ignorant.
Scripture:
Shia: A great emphasis had been put on writing down the sayings of the Prophets and Imams (from day 1) to prevent them from being distorted and to convey them to later generations. Shia scripture is made up of the sayings of the Prophet and infallible Imams. The knowledge that God bestowed upon the Prophet was divinely passed on to the Imams.
Sunni: After the Prophet passed away, for about 100 years, writing of the sayings of the Prophet was prohibited by Sunni Caliphs. After 100 years, the Sunni corpus was formed by what had been passed down orally from one person to another for 100 years, thus rendering them extremely unreliable. Furthermore, the sayings and deeds of the Sahaba (
en.wikipedia.org/wiki/Sahabah ) who were the fallible companions of the Prophet are considered correct solely because they are the ‘Sahaba’. Amongst these companions many were hypocrites who made gruesome errors and even committed serious crimes. For instance on the orders of the first and second Sunni caliphs, the house of the Prophets daughter was set on fire, she was physically abused to the extent that she suffered a miscarriage and subsequently died of her injuries. The Prophets grandsons, al-Hasan and al-Husayn (the second and third Shia Imams) were also ruthlessly murdered by the followers of the same people, as were eleven of the Shia Imams. ISIS follows the same path today.
If you have any questions or other topics in mind I can elaborate.
