Sunan al-Nasa'i The Book of Purification al-Laith bin Sa'd الليث بن سعد Muhammad bin Muslim bin Tadras محمد بن مسلم بن تدرس أبو الزبير Qutayba bin Sa'id bin Jamil قتيبة بن سعيد بن جميل Sufyan bin 'Abdur Rahman سفيان بن عبد الرحمن “O Abu Ayyub, we missed the general mobilization, but we have been told that whoever prays in the four Masjids will be forgiven his sins.” He said: “O son of my brother! I will tell you of something easier than that. I heard the Messenger of Allah (ﷺ) says: ‘Whoever performs Wudu’ as commanded and prays as commanded, will be forgiven for his previous actions.’ Is it not so, O ‘Uqbah?” He said: “Yes.” https://parallelquran.com/hadith/sunan-al-nasai-145/
