For your praying to be accepted does it need to be according to the Prophet's prayer or the ways he permitted? Do you have to put your hands on your chest or on stomach and do you touch your ear lobes at opening prayer, when lowering, and raising from Rukuh or do you have to raise your hand to the level of your shoulders for your praying to be accepted. Also do you have to put your hand on your chest (or stomach) with right hand over left wrist when standing after raising from Rukuh?

Praise be to Allah, the Lord of the World; and blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.
There are only four authentic forms of raising hands during prayer.
1. Raising hands above the ears.
2. Raising hands until they become parallel to the ears.
3. Raising hands till they become opposite to the shoulders.
4. Raising hands up to the chest.
For your other questions, please refer to the Fatwa: 82692, 83175 and 82421.
Allah knows best.
