Times of wiping one's head in Wudu'

Q: How many times should the head be wiped over during Wudu' (ablution)? If someone performs Wudu’ in their home and then goes to the Masjid (mosque), but when they get there they remember that they did not wipe their head, what should they do?

A: All praise be to Allah Alone, and peace and blessings be upon His Messenger, and his family and Companions. It is obligatory to wipe over the head once during Wudu’. Anyone who performs Wudu’ and forgets to wipe their head is obligated to repeat their Wudu’ if a long-time gap intervenes, because continuity is obligatory. However, if they remember during the Wudu’, they should wipe their head and then wash their feet again.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
