(At-Thakhveer) 81 : 4
وَإِذَا الْعِشَارُ عُطِّلَتْ
When she-camels are about to give birth are unattended.
In all periods, Arabs have been very careful with she-camels that are about to deliver. This verse informs that, due to the horror of the Last Day, they will not pay attention even to such pregnant camels. See explanation 22: 1-2.
