bayhaqi:16550Abū Bakr

[Machine] "And Abu Bakr said in his sermon on that day, 'Abu Abdullah Al-Hafiz informed us, who narrated from Abu Al-Abbas Muhammad ibn Ya'qub, who narrated from Ahmad ibn Abd Al-Jabbār, who narrated from Yunus ibn Bukayr, who narrated from Ibn Ishaq in his sermon on that day. He said, 'It is not permissible for Muslims to have two leaders, for even if that were to happen, their affairs and rulings would differ, their groups would separate, and they would dispute amongst themselves. In that situation, the Sunnah would be neglected, innovations would appear, and unrest would increase. And no one will benefit from it.'"

وَقَالَ أَبُو بَكْرٍ ؓ فِي خُطْبَتِهِ يَوْمَئِذٍ مَا أَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ ثَنَا أَبُو الْعَبَّاسِ مُحَمَّدُ بْنُ يَعْقُوبَ ثَنَا أَحْمَدُ بْنُ عَبْدِ الْجَبَّارِ ثَنَا يُونُسُ بْنُ بُكَيْرٍ عَنِ ابْنِ إِسْحَاقَ فِي خُطْبَةِ أَبِي بَكْرٍ ؓ يَوْمَئِذٍ قَالَ وَإِنَّهُ لَا يَحِلُّ أَنْ يَكُونَ لِلْمُسْلِمِينَ أَمِيرَانِ فَإِنَّهُ مَهْمَا يَكُنْ ذَلِكَ يَخْتَلِفْ أَمَرُهُمْ وَأَحْكَامُهُمْ وَتَتَفَرَّقُ جَمَاعَتُهُمْ وَيَتَنَازَعُوا فِيمَا بَيْنَهُمْ هُنَالِكَ تُتْرَكُ السُّنَّةُ وَتَظْهَرُ الْبِدْعَةُ وَتَعْظُمُ الْفِتْنَةُ وَلَيْسَ لِأَحَدٍ عَلَى ذَلِكَ صَلَاحٌ
