A--- Birinchi: bu ibodatning butun amalini bekor qiladi, masalan, Bomdod namoziga uchinchi rakat qo'shish, Shom namoziga to'rtinchi, yoki Peshin namoziga beshinchi rakat qo'shish. Yoki undan bir rakatni kamaytirish.

A--- First: it nullifies the whole act of worship such as adding a third Rak'ah to the Fajr Prayer, a fourth one to the Maghrib, or a fifth to the Zuhr Prayer. Or, such as decreasing a Rak' ah thereof.

Ikkinchidan: bu ibodatni batil qilmaydi, garchi u (bid'at) bo'lsa ham.

Second: it does not nullify the act of worship though it is (Innovation)

...itself is basically nullified. Masalan, wudu'da a'zolarni yuvishning to'rtinchi marta qilinishini qo'shgan kishi kabi. Payg'ambar ﷺ bu (amal) batil bo'ladi, demadilar, balki: "Kim bunga (ortiqcha) narsa qo'shsa, u albatta yomonlik qildi, haddan oshdi va xato qildi", dedilar. (Abu Dovud va Ibn Moja)

itself is basically nullified. Such as the one who adds a fourth time of wash to the organs to be washed in Ablution. The Prophet (Peace be upon him) did not say it is nullified, but said: "Whosoever adds to this, he certainly did badly, transgressed and did (something) wrong." (Abu Dawud and Ibn Majah)
