There is a Hadith which means that the Salah (prayer) of a person will be interrupted if a woman, a black dog or a donkey passes in front of the person offering Salah. The question is: Does the Salah become nullified (Part No. 7; Page No. 82) in this case? Or is the reward minimized?
If Salah becomes nullified, what is the distance that should be kept between the person offering Salah and whoever passes ahead?
The right opinion is that the passage of the previously mentioned in front of the one offering Salah, or between the person and their Sutrah (barrier placed in front of a person praying) nullifies Salah, for what is authentically reported that the Prophet (peace be upon him) said:
Salah is interrupted by the passage of a woman, a donkey, or a black dog, but if something like a rear part of a saddle is placed ahead, it shall guard against disrupting the Salah.
Muslim in his Sahih (Authentic book of Hadith). On the other hand, it was said that: Salah does not become nullified by such things, rather the reward becomes minimized for the lacking of submissiveness in Salah whether fully or partially. However, it is clear that the first opinion is the correct one, as the second opinion has no reliable evidence.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
