Reason Of Muhammad (SAW)'s Death
After publishing the question, I visited the hadith myself. Here the subject is different and also it has been written that Hazrat Muhammad (SAW) told the companions that it (bolus of piece of lamb) said it was poisoned and so he (SAW) spit it out but the poison started showing effects since then. So, I think it was the condition of Jews that was fulfilled that if he (SAW) was a messenger, Allah would inform him of it. But I want to know whether it is true that his last bad condition was due to this or not?
