In some cases, you may never see someone who was her ablutions but he did not take off his shoes, but just brushed the tip of his shoe.
It is actually not a heresy or fetched because Rasul has ever done. Based on ulema and scholars it called khuf and following hadith.
From al-Mughirah bin Shu'bah ra, he said: "I was on the way with the Holy Prophet on a night. Then he asked:" Did you bring water? "I replied:" Yes. "He then fell off his bike and walked so closed in the darkness of the night. then he came back. So on I poured water on him to purify himself. he saw then washed his face and he was wearing - a long dress to the knee - made of fur, then he can not remove his arms from clothes it - because of the narrowness of the aperture of the hand - that excluded the one his arms from under the cloak. Then he saw washed his arms and rubbed his head. After tu me down to the bottom was about to release the second shoe khufnya, but he Allah said: "Let alone both shoes that, because I actually put it in a state of purity, so he saw rubbed over the second shoe. "(muttafaq 'alaih)
In another narration: "He was wearing artificial s.a.w. Syam country - ie, Palestine - the second narrow hole hands.
In another report, it says that this poristiwa -that is, as described above - is happening in the battle of Tabuk.
From the hadith above, it is clear that the Apostle did not take off his shoes at the time of purification ritual but in some of the criteria and requirements include:
1. Khuf Rasul times not the same as today
As we know today the shoes have various shapes, in contrast to the days of the Apostles in the case of the above Hadith on the way, so if released these shoes take a long time and release another piece of clothing.
2. In a state of purity before entering into the shoes
As mentioned, that the Apostle in a state of purity at the time put his foot into the shoe. And this is a requirement that the person who rubbed his khuf later should prepare ahead of time with a state of purity before wearing shoes.
But unfortunately there is no history that says whether the trip was canceled wudhunya Apostles or remained chaste despite her ablutions again. Because, as the Apostle in other traditions disunnahkan if you like prayers berwudhulah again though in a state of purity.
3. Lightweight, instead of seeking waivers
Rasul doing so, because the state of the load he was doing that so as to provide ease and lightness in a purification ritual but in case we are in a state of airy and easily then do not search for lightness and ease yourself. Like shoes that can be removed in a time of 1 minute, then there is no harm if released and ablution.
Many cases of people who were given relief and ease in religion but is used to find the ease and lightness that indulgence and underestimate worship.
Thus the discussion about the law khuf (swiped boots when ablution), hopefully we can implement all the Shari'a well, full of confidence and accepted by Allah.
