Mola Ali (a.s) Ibn e Abu Talib (a.s) heard somebody reciting the passage of the Holy Qur'an "We belong to Allah and our return is towards Him", Mola Ali (a.s) Ibn e Abu Talib (a.s) said:
"How true it is! Our declaring that we belong to Allah indicates that we accept Him as our Master, Owner and Lord. And when we say that our return is towards Allah indicates that we accept our mortality".
