Translation of the verse 4 from Surah At-Takwir : Number of verses 29 - - page 586 - Part 30.
And when the pregnant she-camels shall be neglected;
And when full-term she-camels are neglected
(81:4) when the ten-months pregnant camels shall be abandoned, *4
*4) This was by far the best way of giving an idea of the severities and horrors of Resurrection to the Arabs. Before the buses and trucks of the present day there was nothing more precious for the Arabs than the she-camel just about to give birth to her young. In this state she was most sedulously looked after and cared for, so that she is not lost, stolen, or harmed in any way. The people's becoming heedless of such she-camels, in fact, meant that at that time they would be so stunned as to become unmindful of their most precious possessions.
