فصرح في هذا الخبر أن من ادرك ركعة فقد ادرك الجمعة فلو لم يكن المراد بالخبر الاول ما ذكرناه لتناقضا وهذا فاسد
So, it is explicitly stated in this narration that whoever catches one rak’ah has caught the Friday (prayer). Therefore, if the meaning of the first narration were not what we have explained, the two narrations would contradict one another and that is invalid.
