The Dalai Lama says that without the human community one single human being cannot survive.
Without the human community, one single human being CAN survive if Allah wants him to survive, and if he has Allah in his life.
There are countless examples of this that have been preserved in the pages of history.
One doesn't need other people to survive. The only thing needed is Allah's help, and to have firm Iman and trust in Allah, and in the power and might of Allah.
