About wudhu has been described by Allah in QS Al-Maidah: 6: O you who have believed, when you rise to [perform] prayer, wash your faces and your forearms to the elbows and wipe over your heads and wash your feet to the ankles. And if you are in a state of janbah, then purify yourselves. But if you are ill or on a journey or one of you comes from the place of relieving himself for you have contacted women and do not find water, then seek clean earth and wipe over your faces and hands with it. Allah does not intend to make difficulty for you, but He intends to purify you and complete His favor upon you that you may be grateful.Wamsahuu blueusikum (sapulah kepalamu), the scholars differ ininterpreting the meaning of imsah:
- It could mean sweeping across the head as in the hadith of Abdullah bin Zaid narrated by the Jamaah: The Prophet wiped his head with both hands, and he moved his hands from face to back. That is, he wipe his hands that have been attached to the head starting from the front of his head, then he pulled his hands toward the shoulders, then pulled back to where the beginning started a head sweep.
- It may mean sweeping the turban just as in the hadith of Amar bin Umaiyah, “I saw the Messenger of Allah swept the turban and both his shoes – when performing ablution.” (Ahmad, Bukhari, Ibn Majah). In Bilal’s account, the Holy Prophet said, “Sweep both your shoes and the scarves or the headgear.” (HR Ahmad)
- It could mean sweeping the top of the head and the turban as Mughiroh ibn Shubah’s hadith, that the Prophet saw ablution and then swept the top of his head, his turban, and so did his two shoes. (Muslim)
From this explanation, Muslim women who wear a veil may wipe his head / top of his head, then wiped his veil when performing ablution outside the house.
How to perform tayamum (ablution with soil) in the hadith Ammar ra, “I am janbah and do not get water, so I was covered with soil, then praying.” Then I told it to the Messenger of Allah, he said, “(In bertayamum) you simply do like this: Put his palms to the ground, then he blew the two hands full of dust, then swept to the face and then swept them into his hands. “(Bukhari and Muslim)
Another Hadith narrated by Daruquthni, “It is enough if you strike your palms to the ground, then blow the hand that has been filled with the soil and then sweep it to your face and to both hands to the wrist.” Based on this hadith, the hands dusted only until Wrist only.
