Ablution, or Wudhu in Arabic, is the act of cleansing and purifying with water. Cleanliness is essential to the Islamic faith. Muslims perform ablution before Salat (daily prayers) and supplication because Allah (سُبْحَانَهُ وَتَعَالَى) loves those who make a habit of remaining clean. The Sunnah of Prophet Muhammad (ﷺ) is an infinitely living beacon, guiding Muslims to be the best versions of themselves. We learn with diligently preserved hadiths the hows and whats of performing ablution, from the beginning to the end.
Ablution or Wudu is an essential requirement for performing any worship, especially when standing for prayer (salah), as mentioned in the 6th verse of Surah Al-Ma’ida.
Translation of the first part of the verse – O believers, when you stand up for the service of prayer, wash your faces and hands up to elbows, and also wipe your heads, and wash your feet up to the ankles.
This verse not only enjoins making ablution before the performance of Salah but also provides guidance on how to make ablution. Islam is very particular about purity and cleanliness, physically and spiritually. Wudu is an act that fulfills both these requirements. When we start with the dua for performing ablution, it not only cleanses us physically but also brings spiritual purification.
When starting ablution, Muslims must begin with the name of Allah (سُبْحَانَهُ وَتَعَالَى). We learn this through Abu Hurayrah (رَضِيَ ٱللَّٰهُ عَنْهُ ) in Sunan Abi Dawud 101, that the Messenger of Allah (ﷺ) said: The prayer of a person who does not perform ablution is not valid, and the ablution of a person who does not mention the name of Allah (in the beginning) is not valid. Again, in Sunan Ibn Majah (398), Abu Sa'eed bin Zaid (رَضِيَ ٱللَّٰهُ عَنْهُ) recalls Prophet Muhammad (ﷺ) saying: 'There is no prayer for one who does not have ablution, and there is no ablution for one who does not mention the Name of Allah (before it). These hadiths clearly illustrate the importance of beginning ablution with the name of Allah (سُبْحَانَهُ وَتَعَالَى).
Bismillaahi - بِسْمِ اللّهِ (in the name of Allah)
Some scholars also recommend reciting Dua before wudu as follows:
Bismillāh-ir-Raḥmān-ir-Raḥīm - بِسْمِ اللہِ الرَّحْمٰنِ الرَّحِيْمِ (In the name of Allah, most benevolent, ever-merciful.)
However, the most recommended and popular wudu ablution dua is the shorter version “Bismillahi."
(I start) In the name of Allah.
So, when we start wudu with the name of Allah سُبْحَانَهُۥ وَتَعَالَىٰ, it brings plenty of His Blessings, expiating all sins committed through the eyes, hands, and feet.
Etiquettes of wudu (Adab-e-Wudu) include the following:
Ensure the cleanliness of the place of wudu.
No dua is prescribed for recitation during the course of performing wudu or ablution. Dua is required to be recited while starting the wudu.
Yes, there is nothing wrong with reciting the complete version "Bismillāh-ir-Raḥmān-ir-Raḥīm" before the performance of ablution. It is permissible in Islamic teachings. However, the majority of scholars recommend that simply reciting "Bismillahi" is sufficient, as is evident from Hadith 101 of Sunan Abu Dawood.
The majority scholarly opinion on this issue is that even if you forget to say Bismillah before starting wudu, your wudu is still valid because it is not obligatory but strongly recommended.
The best practice is to recite Bismillah silently before starting ablution.
