I believe the conditions for repentance are as follows: (correct me if I'm wrong)
1. Leaving the sin;
2. Remorse over having committed the sin;
3. Resolve never to return to the sin;
4. (If it relates to the rights of another person, then to) Return the rights or property one wrongly took.
I know this sounds basic, but is making tawbah rather like making a du'a to Allah (i.e. lifting your hands to around shoulder height and asking for forgiveness?)
Is that the way one makes tawbah?
Also, do you have to be in a state of purity (wudu) if your making tawbah?
