Sahih al-Bukhari 160
Book 4: Ablutions (Wudu') · Hadith 26
Hadith text
After performing the ablution 'Uthman said, "I am going to tell you a Hadith which I would not have told you, had I not been compelled by a certain Holy Verse (the sub narrator 'Urwa said:This verse is: "Verily, those who conceal the clear signs and the guidance which we have sent down...)" (2:159). I heard the Prophet (ﷺ) saying, 'If a man performs ablution perfectly and then offers the compulsory congregational prayer, Allah will forgive his sins committed between that (prayer) and the (next) prayer till he offers it
Wudu ke baad Uthman ne kaha: "Main tumhe woh hadith bataunga jo agar Quran ki ek ayat na hoti to na bataata: 'Beshak jo log woh saaf nishaniyaan chhupaate hain jo humne nazil ki...' (2:159). Maine Nabi (ﷺ) ko farmate suna: 'Jo mukammal wudu kare aur farz namaz jamaat ke saath padhe, Allah uske gunah is namaz aur agli namaz ke darmiyan maaf kar dega.'"
