And Allah says:
All humility and fear should be for Allah and not any human or person. This is in opposition to the deviant groups (such as the sufis) who crawl to their so called "saints"; then bow to them and show an excessive veneration toward them. Only Allah deserves such humility.
A person should supplicate to Allah for forgiveness. And should be aware of shirk. There is an authentic supplication for this: For fear of shirk:
