باب كَرَاهَةِ الشُّرُوعِ فِي نَافِلَةٍ بَعْدَ شُرُوعِ الْمُؤَذِّنِ:
Chapter: It is disliked to start a voluntary prayer after the Mu’adhdhin has started to say Iqamah for prayer, whether that is a regular sunnah, such as the sunnah of Subh or Zuhr, or anything else, and regardless of whether he knows that he will catch up with the rak`ah with the Imam or not

وحَدَّثَنِي يَحْيَى بْنُ حَبِيبٍ الْحَارِثِيُّ ، حَدَّثَنَا رَوْحٌ ، حَدَّثَنَا زَكَرِيَّاءُ بْنُ إِسْحَاق ، حَدَّثَنَا عَمْرُو بْنُ دِينَارٍ ، قَالَ : سَمِعْتُ عَطَاءَ بْنَ يَسَارٍ ، يَقُولُ : عَنْ أَبِي هُرَيْرَةَ ، عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، أَنَّهُ قَالَ : " إِذَا أُقِيمَتِ الصَّلَاةُ ، فَلَا صَلَاةَ إِلَّا الْمَكْتُوبَةُ " .
Abu Hurairah (RA) reported the Apostle of Allah (ﷺ) as saying: When the prayer commences, there is no prayer but the obligatory one.
