Mother is heaven, but heaven is not mother,
Because mother is greater than heaven.
First time, mother's womb was heaven of her child,
Because no food is taken directly by it but he is alive.
Mother takes food, but nutrition was taken by her child,
When he stayed his mother's womb with sleeping,
Because it is most kindness of Allah's blessing.
Mother is heaven, but heaven is not mother,
Because heaven stays underfoot of mother.
So mother is the greatest blessing of God.
