[Machine] The Messenger of Allah ﷺ said: "Whoever catches a raka'ah (unit of prayer) before the imam stands up straight, then he has caught it." Abu Ahmad said: "This additional statement "before the imam stands up straight" is said by Yahya bin Humaid from Qura and he is Egyptian. Abu Ahmad said: "I heard Ibn Hammad say that Al-Bukhari said: Yahya bin Humaid from Qura from Ibn Shihab heard it from Ibn Wahb who is Egyptian, and his hadith is not continuously transmitted." Abu Ahmad said: "And Jundaidi narrated from Al-Bukhari, he said: Yahya bin Abi Sulayman Al-Madani from Al-Maqburi and Ibn Abi Atab, a discredited narrator of hadith." The sheikh said: "And it has been narrated with a Mursal isnad (broken chain of narrators)."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَنْ أَدْرَكَ رَكْعَةً مِنَ الصَّلَاةِ فَقَدْ أَدْرَكَهَا قَبْلَ أَنْ يُقِيمَ الْإِمَامُ صُلْبَهُ قَالَ أَبُو أَحْمَدَ هَذِهِ الزِّيَادَةُ قَبْلَ أَنْ يُقِيمَ الْإِمَامُ صُلْبَهُ يَقُولُهَا يَحْيَى بْنُ حُمَيْدٍ عَنْ قُرَّةَ وَهُوَ مِصْرِيٌّ قَالَ أَبُو أَحْمَدَ سَمِعْتُ ابْنَ حَمَّادٍ يَقُولُ قَالَ الْبُخَارِيُّ يَحْيَى بْنُ حُمَيْدٍ عَنْ قُرَّةَ عَنِ ابْنِ شِهَابٍ سَمِعَ مِنْهُ ابْنُ وَهْبٍ مِصْرِيٌّ لَا يُتَابَعُ فِي حَدِيثِهِ قَالَ أَبُو أَحْمَدَ وَثنا الْجُنَيْدِيُّ ثنا الْبُخَارِيُّ قَالَ يَحْيَى بْنُ أَبِي سُلَيْمَانَ الْمَدَنِيُّ عَنِ الْمَقْبُرِيِّ وَابْنِ أَبِي عَتَّابٍ مُنْكَرُ الْحَدِيثِ قَالَ الشَّيْخُ وَقَدْ رُوِيَ بِإِسْنَادٍ مُرْسَلٍ
