i have 2 questions regarding this hadit below... my first question is regarding #5 in the hadith below... does this mean to fast? and my second question is regarding #6... does this mean to have my brain and heart that writhing pain that seems to come over my body as i remember my sin? is that the correct pain of obediennce ?? or is there a solace a blissfulness in being obedient in doing something i truly want to do an truly find Repentance?? It is narrated that someone said: Astaghfirullah (I seek God's forgiveness) before Imam ‘Ali Úáíå ÇáÓáÇã. He said to him. "May your mother mourn for you! Do you know what istighfar is? Verily istighfar is a degree of the 'illiyyun (people of high station) and it is a word that means six things. First is remorse over the past. Second, the resolution not to return to it ever. Third, to return to creatures their (formerly usurped) rights so that you meet God Almighty in a state of purity in which no one has any claim against you. Fourth, that you fulfil every duty that you neglected in order to satisfy your obligation in respect to it. Fifth, that you attend to the flesh of your body that has grown on unlawful nourishment so that it melts away as a result of grief and mourning and your skin adheres to your bones, after which new flesh grows in its place. Sixth, that you make your body taste the pain of obedience in the same way as it earlier tasted the pleasure of sins. When you have done these things then say Astaghfirullah!
