Minor ritual impurity while offering Salah invalidates it

Q 1: We ask about some rulings regarding Salah (Prayer) which we read in a book called "Kashful-Ghummah ‘An Jami‘ Al-Ummah," vol. 1, pp. 107-108. We would like to know whether such rulings are sound or not. Following are the rulings:The Prophet (peace be upon him) said: “If one of you goes into a state of (minor) ritual impurity (i.e. Breaks wind) during his Salah, let him hold his nose and then leave (Salah).” This person then should perform Wudu’ (ablution) and return to resume his Salah as long as he has not spoken.

A: This Hadith is judged to be Da‘if (a Hadith that fails to reach the status of Hasan, due to a weakness in the chain of narration or one of the narrators) by some Hadith scholars. Therefore, its indication, i.e. that the person who goes into a state of minor ritual impurity (passes wind, urinates, or defecates) during Salah should leave his Salah, perform Wudu’, and return to complete his Salah, is unsound. Rather, passing wind, urinating, or defecating invalidates Salah. Thus, such a person has to start Salah anew after repeating Wudu’. This is indicated by the Hadith reported on the authority of `Aly ibn Talq (may Allah be pleased with him) that the Messenger of Allah (peace be upon him) said: “If one of you breaks wind during Salah, he should leave (Salah), perform Wudu’ and then repeat the Salah.” (Related by Ahmad, Abu Dawud, Al-Tirmidhy, Al-Nasa'y, and Ibn Majah and ranked as Sahih [authentic] by Ibn Hibban) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
