Translation of the verse 21 from Surah Al-Mursalat : Number of verses 50 - - page 581 - Part 29.
Then We placed it in a place of safety (womb),
And We placed it in a firm lodging
(77:21) which We then placed in a secure repository *11
*11) "A secure place": the mother's womb in which the child is so firmly lodged as soon as it has been conceived and where such arrangements are made for its security and nourishment that abortion cannot take place unless there is a disaster, and even for artificial abortion extraordinary devices have to be adopted, which are both risky and harmful in spite of modern developments in medical science.
