من قال: لا يقطع الصلاة شيء وادرأوا ما استطعتمIf someone passes in front of a praying person, salah is not invalidated but he should try to prevent it
Hadith 2922
٢٩٢٢ - حدثنا ابن فضيل عن ليث عن طاوس عن ابن عباس (قال) (١): اعزلوا صلاتكم ما استطعتم، وأشد ما (يتقى) (٢) عليها مرابض الكلاب (٣).
Hazrat Ibn Abbas (may Allah be pleased with them) says that as much as possible, prevent those passing in front of you; among the things from which it is most necessary to be cautious about passing in front during prayer, dogs are foremost.
