After taking the fodder they swam across the river till they came upon an eddy. Numerous of them would lift their heads relying on Sahar's help. The buffaloes would happily and helpfully reach the other bank; (The believers passed their life in this world and reached the Prophet of Islam who would, lnsha Allah, help them at that stage and finally lead them to Paradise).
Note:The poet has likened the grave to a vortex in this verse, to the 'pul sirat', and to a well in the next verse.

Buffaloes had their fodder, crossing the deep,
reached the well,
With raised heads hundreds respond to Mehar's call,
With safety and peace, they will reach the other strand.

Having graze pasture, the buffaloes swam and neared whirlpool,
Millions will raise their heads at Sahar's call,
The buffaloes will happily reach the other bank in peace.
