As per your friends situation he's been charged under sections 323 and 506 (Indian Penal Code, 1860) IPC for "Voluntarily Causing Hurt" and "Criminal Intimation" respectively.
In order to prove your friend innocent you need to prove that the intention of filling the FIR was guilty.
This can be done by obtaining the discharge certificate as well as the LAMA (Leave Against Medical Advice) or DAMA (Discharge Against Medical Advice) certificate from the hospital, such that it can be proved that the person has not even indulged in proper medical treatment and thereby has fled the hospital before without medical advice (which signifies that the intention was not pure).
Along with these you may file a formal complaint with the respective police station, stating that the complaint filed against you is fraudulent and none of the activities stated in it were true, thus resulting in rejection of the FIR.
