The Virtue of Perfect Wudhu’ and its Du'ā.
In the name of Allāh, the Most Gracious, the Most Merciful;
All the praise and thanks is due to Allāh, the Lord of al-‘ālamīn. I testify that there is none worthy of worship except Allāh, and that Muhammad, Sallallāhu ‘alayhi wasallam is His Messenger.
It is reported by way of ‘Umar Ibn Al-Khattab (radiyallāhu‘anhu) that the Prophet (Sallallāhu ‘alayhi wasallam) said:
“There is not one of you that make wudhu', and performs the rites of wudhu', when he has completed his wudhu', then says:
‘Ash-hadu an lā ilāha illallāhu wahdahu la sharīka lahu, Wa anna muhammadan ‘abduhu wa rasūluh,
( I bear witness that there is no ilāh except Allāh alone, no partner has he, and that Muhammad is His bondservant, and Messenger.);
Except that the eight gates of Heaven would open up for him, that he may enter from whichever he would please”.
This hadith is no.162 in his Sahīh Abu Dawud, and no.96 in ‘Al-Irwā’ . It is also recorded by Muslim, An-Nasā’ie and Ahmad. Al-Albāni said it was sound in his Sahīh Al-Jãmi’ As-Saghīr wa Ziyādatih.
In another narration it was reported by way of Abu Sa‘eed (radiyallāhu‘anhu) that the Prophet (Sallallāhu ‘alayhi wasallam) said:
“Whoever performs wudhu' then after completion it says: Subhānaka allāhumma wa bihamdika, ash-hadu an lā ilāha illa anta, Astaghfiruka wa atūbu ilayk,
(Glorified are You O' my ilāh and I am in Your praise, I testify that there is no ilah except You, I ask Your forgiveness and repent unto You.)
It would be written on vellum then sealed; thereafter, it would not be broken till The Day of Resurrection".
This recorded by An-Nasā’ie, and Al-Hakim Al-Albāni said it was sound in ‘Sahih Al-Jāmi as-Saghīr wa Ziyādatih.
‘Uqbah Ibn ‘Amr (radiyallāhu`anhu) related that the Allāh’s Messenger (Sallallāhu ‘alayhi wa sallam) said:
“If one performs and perfects his wudhu’ and perform solah two raka’at (Nawafil al-Wudhu’) with his heart and face (completely on his solah); Paradise becomes his.”
This is recorded by Muslim, Abu Dawud, Ibn Mājah and Ibn Khuzaimah.
And Allāh Almighty knows best.
