Man comes from a drop of semen and leaves as a piece of dust. He doesn't know when he came and he doesn't know when he's leaving, yet he walks on the earth thinking he knows everything.
Ali ibn Abi TalibPeople are of two types, they are either your brothers in faith or your equals in humanity.
Ali ibn Abi TalibHow strange and foolish is man. He looses his health in gaining wealth. Then to regain health he wastes his wealth. He ruins is present while worrying about his future - but weeps in the future by recalling his past. He lives as though death shall never come to him - but dies in a way as if he were never born.
