It is He Who has created you from one living entity, and from the same stock (that He created a human being) He brought into being his mate that he might find comfort in her. When he covers her (in conjugal relationship) she conceives a light burden and carries it about, then when she grows heavy (with the child), they both pray to Allâh, their Lord, (saying) `If You give us a good one (- a child with a sound mind in a sound body), we shall surely be of the grateful (to You).'
