Man say he only want Allah, his messenger Muhammad (PBUH) and next is his family

Man say he do not want anybody except Allah and his messenger 

He say he believe Allah strongly and he love Muhammed (pbuh)

Man say he firmly believe in Allah and he worship Him day and night

Man say whenever he want he repent, perform Ihtikaf, istigfar, do sajada and seek forgiveness from Allah

He perform Umrah and Hajj

He strongly believe that all his sins are pardoned and forgiven by Allah and he gives him rewards

Because his faith is very strong

Meantime since he have recited the Kalima

After the Hellfire, he will be permitted to enter Paradise and he will get everything he wish 

Can this happen ?

Can a man who is dishonest, greedy, selfish, coward, proud and egoist to his fellowmen believe, worship and repent to Allah and love prophet whom he has not seen or met ?

However

in Spiritual Islam

A believer is a person who does not sin

A none-believer is a person who sin

However

Believe in God not in words but in attributes of humanity

At the same time

Disbelieve in God not in words but in attributes of inhumanity
