Does Allah print upon the heart of a Muslim, and how does that happen, what are its implications, and is there a remedy for it?

Sealing of hearts occurs for the hearts of disbelievers, and it is a complete sealing of the entire heart. It also occurs for the hearts of disobedient Muslims, and it is a partial sealing depending on the disobedience. This sealing is a punishment for the disbelief of disbelievers and the disobedience of Muslims. The sealing of the hearts of disobedient Muslims occurs due to the abundance of sins and transgressions, exposure to trials of desires and doubts, and abandoning Friday prayers out of negligence. To be saved from this, a servant must recognize the sin committed, repent, seek forgiveness, reject temptations, and adhere to a state of neediness towards Allah by seeking guidance and opening the heart to light.
