Ibn Bazz: Ruling on forgetting to wipe one's head when performing Wudu'

Ruling on forgetting to wipe one's head when performing Wudu' 

Q: While performing Wudu' (ablution), I forgot to wipe my head but I washed my feet. Am I obliged to re­perform Wudu' from the beginning? Or should I just wipe my head and then rewash my feet? 

A: You should wipe your head and ears and then rewash your feet if you remember this shortly after performing Wudu'. But if you remember this after a long time from performing Wudu', you should re­perform Wudu' from the beginning because close sequence in washing your parts is obligatory in performing Wudu'. May Allah grant us success!
