And when full-term she-camels are neglected (81:4)

Almuntakhab Fi Tafsir Alquran Alkarim

The precious pregnant she - camels are forsaken

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(81:4) when the ten-months pregnant camels shall be abandoned, *4

And when full-term she-camels are neglected meaning

*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.
