Q: If a person is making wudhu and the feet cannot be washed at the same time, can the feet be washed at a later time?
A: Wilaa (sequence) is from the Sunnah acts of Wudhu which means that under normal circumstances, the next limb be washed before the previous limb becomes dry. Therefore, in the enquired scenario, it is advisable that there be no unnecessary delay in washing the feet such that by the time the feet are washed, the other limbs are dry. However, if this was done, then the Wudhu is valid.
Further, if there is a valid excuse for such delay, then Insha Allah one will not be deprived of the reward of this Sunnah.
And Allah Knows Best
