(See Hadith No. 409, Vol 9).

Once the Jews came to the Prophet and said, "Death be upon you." So I cursed them. The Prophet said, "What is the matter?" I said, "Have you not heard what they said?" The Prophet said, "Have you not heard what I replied (to them)? (I said), ('The same is upon you.')"

Allah's Apostle in his fatal illness said, "Allah cursed the Jews and the Christians, for they built the places of worship at the graves of their prophets."

So (the Prophet ) was afraid, or the people were afraid that his grave might be taken as a place for worship.

`Aisha said, "The Prophet said during his fatal illness, "Allah cursed the Jews for they took the graves of their prophets as places for worship." `Aisha added, "Had it not been for that (statement of the Prophet ) his grave would have been made conspicuous.

Sahl bin Sa’ad said “The version of Musaddad has “I witnessed the invoking of curses by the two spouses during the life time of the Apostle of Allaah(saws) when I was fifteen years old.

Regarding: 'And We granted the vision (Ascension to the Heaven "Miraj") which We showed you (O Muhammad as an actual eye witness) but as a trial for mankind.'

When the last moment of the life of Allah's Apostle came he started putting his 'Khamisa' on his face and when he felt hot and short of breath he took it off his face and said, "May Allah curse the Jews and Christians for they built the places of worship at the graves of their Prophets."

When the disease of Allah's Apostle got aggravated, he covered his face with a Khamisa, but when he became short of breath, he would remove it from his face and say, "It is like that! May Allah curse the Jews Christians because they took the graves of their prophets as places of worship." By that he warned his follower of imitating them, by doing that which they did.
