If you do not maintain respect and discipline in front of the Prophet...
If you do not maintain respect and discipline in front of the Prophet, your deeds become null and void. Here deed means your worship through your presence before the Holy Prophet. If you have hurt him, it is a great sin that equals disbelief or blasphemy. You have destroyed your deed with your own hands. Apostasy nullifies deeds Another probability, described by some of the commentators of Qur’an is that it means total nullification.
Nullifying of a deed by another deed is something not easily understood. Whatever Qur’an says must be accepted. The Holy book clearly states that there are some sins, which if committed, nullify all previous good deeds. Foremost among them are disbelief and apostasy. May God save the one who offers prayer till the age of thirty, observes fasts and even performs Hajj.
Then if he gets a lot of money and travels to centers of sin and evil, after being lured buy them and says, “We were mad that we observed fasts in hot summers and deprived ourselves from drinking, enjoyment and gambling. Why did we go for Hajj and spend a lot of money? The Arabs ate our wealth.” If he utters such words then his previous good deeds go in vain. If he dies in this condition, he will not have in his credit even a two-unit prayer.
It is as saying goes; the cow gave milk but also kicked it and spilled it all. If one turns away from his religion (apostatizes), definitely there is a permanent chastisement for him. There is no way of salvation for him. All the deeds which he had done have gone in vain. He himself has nullified them. A man’s turning apostate! What it means? He himself says: I did it unnecessarily; I prayed prayer uselessly. Is there any more prayer for him? He himself says: I performed Hajj needlessly.
Is there any Hajj for him or at his credit any more? Woe unto such a fellow who ruined his future. In short, if one reverts to disbelief his good deeds are gone. One who hurts the Prophet nullifies his good deeds Among other sins, which nullify good deeds and amount to disbelief is harming or hurting the feelings of the Prophet. Qur’an mentions it very clearly that one who annoys the Prophet and hurts him, each and every good deed of his would go in vain. This is very clear.
If one hurts the Prophet it is as if he denies his Prophethood and Messengership. So every good deed performed by him earlier is now null and void. Except this misdeed, there is no other sin, which washes out previous good deeds completely.
