ارْكُضْ بِرِجْلِكَ هَذَا مُغْتَسَلٌ بَارِدٌ وَشَرَابٌ
[We told him:] ‘Stamp your foot on the ground; this [ensuing spring] will be a cooling bath and drink.’
Agha Ali Puya Commentary
Commentary on Quran 38:42
[Pooya/Ali Commentary 38:42] Ayyub was commanded by Allah to strike at a rock from which two springs of hot and cold water gushed forth. Hot water was to wash his body to get rid of all physical ailments and cold water to drink and refresh his spirits.
