What is the ruling on wudu' if the order or continuity is missed due to forgetfulness?

The Shaykh : As for a person's excuse in these two matters due to forgetfulness or ignorance, it is a matter of consideration. The well-known view among the Hanbali jurists (may Allah have mercy on them) is that a person is not excused in these two matters by ignorance or forgetfulness. If a person begins by washing his hands before washing his face while forgetting, he must repeat the wudu'. If he delays washing a limb after the one before it by a time that separates them, he must repeat the wudu'. There is no doubt that this opinion is the most cautious and the one that clears the conscience. If a person misses the order, even due to forgetfulness, he repeats the wudu'. Likewise, if he misses the continuity, even due to forgetfulness, he repeats the wudu'.
