[Machine] The Prophet of Allah ﷺ came to the Masjid of Quba' or entered the Masjid of Quba' after the sunrise. Suddenly, they (the people) were praying. He said, "Verily, the prayer of the Awaboon (i.e., those who constantly turn towards Allah in repentance) is to be performed when the sun declines from its zenith."  

أحمد:١٩٣٤٧ – حَدَّثَنَا عَبْدُ الْوَهَّابِ عَنْ سَعِيدٍ عَنْ قَتَادَةَ عَنِ الْقَاسِمِ الشَّيْبَانِيِّ عَنْ زَيْدِ بْنِ أَرْقَمَ

أَنَّ نَبِيَّ اللهِ ﷺ أَتَى عَلَى مَسْجِدِ قُبَاءَ أَوْ دَخَلَ مَسْجِدَ قُبَاءَ بَعْدَمَا أَشْرَقَتِ الشَّمْسُ فَإِذَا هُمْ يُصَلُّونَ فَقَالَ إِنَّ صَلَاةَ الْأَوَّابِينَ كَانُوا يُصَلُّونَهَا إِذَا رَمِضَتْ الْفِصَالُ

[Machine] The Prophet of Allah ﷺ entered the Quba Mosque while they were praying when the sun had risen. The Prophet of Allah ﷺ said, "Indeed, the prayer of the Awabiin is performed when the (camel's) shadow lengthens."  

الطبراني:٥١١١ – حَدَّثَنَا إِسْحَاقُ بْنُ خَالَوَيْهِ الْوَاسِطِيُّ ثنا الْعَبَّاسُ بْنُ الْوَلِيدِ النَّرْسِيُّ ثنا يَزِيدُ بْنُ زُرَيْعٍ ثنا سَعِيدُ بْنُ أَبِي عَرُوبَةَ عَنْ قَتَادَةَ عَنِ الْقَاسِمِ بْنِ عَوْفٍ الشَّيْبَانِيِّ عَنْ زَيْدِ بْنِ أَرْقَمَ

أَنَّ نَبِيَّ اللهِ ﷺ دَخَلَ مَسْجِدَ قُبَاءَ وَهُمْ يُصَلُّونَ حِينَ أَشْرَقَتِ الشَّمْسُ فَقَالَ نَبِيُّ اللهِ ﷺ «إِنَّ صَلَاةَ الْأَوَّابِينَ كَانُوا يُصَلُّونَهَا إِذَا رَمِضَتِ الْفِصَالُ»
