(It always happened with the previous Messengers as well, they went on with their teachings) till when those Messengers despaired (of believing on the part of their people) and they (the people of their nation) thought that they have been told only lies (in the name of revelations), Our help reached these (Messengers) suddenly, delivering those whom We pleased. Surely, Our punishment is not averted from the people who sever their ties (with Us).
