We know we must repent when we have committed a sin however, what 3 actions expiate major sins aside from repentance? 

Prophet Muhammad (SAW) said: “entrance into Islam, performing hajj or migrating for the sake of Allah.” The issue is, what if you do not have the opportunity to do those things? The Prophet (SAW) taught us that sincere repentance can do away with anything. So never reject taubah!
