Why Istighfar is So Strong (Hadith)

Seek forgiveness for your sins from Allah, because the most important thing a servant can ask of his Lord is forgiveness for his sins or what necessarily follows from it, such as being saved from Hell and admitted into Paradise. The servant needs his Lord's forgiveness because he slips up every day and every night, and only Allah can forgive all sins. The Messenger of Allah (ﷺ) said: My heart is invaded by unmindfulness, and I ask Allah's pardon a hundred times in the day.
