I asked my Lord three things and He has granted me two but has withheld one. I begged my Lord that my Ummah should not be destroyed because of famine and He granted me this. And I begged my Lord that my Ummah should not be destroyed by drowning (by deluge) and He granted me this. And I begged my Lord that there should be no bloodshed among the people of my Ummah, but He did not grant it.
Sahih Muslim Book 54, Hadith 26
