Salamalaikum. How do you repent from major sins you don't remember? Because when I do taubah I focus on the sin in question and there is guilt associated with my contemplation. I can't get that same feeling from all the unknown sins I have forgotten when I ask forgiveness for all my sins. I keep getting signs from Allah to repent and ask forgiveness but I am at a loss as to what to do next.
Alaikumassalam wa rahmatullah,
According to a fatwa on IslamWeb (operated by the Qatari Islamic Affairs Ministry), it is sufficient to perform a general repentance from all sins. This would apply to the sins you remember and the sins you have forgotten. There is no need to go over them one by one.
It is, of course, best to make it a habit to ask for God’s forgiveness many times every day, both for recent sins and past sins. From Sahih al-Bukhari:
I heard Messenger of Allah (ﷺ) saying: "By Allah, I seek Allah's forgiveness and repent to Him more than seventy times a day." (Sahih al-Bukhari 6307)
Hardships are not always punishments. They could be tests meant to help form your character into something even better by teaching you lessons and showing you your own flaws and errors.
