Sahih al-Bukhari 3596
Narrated 'Uqba bin 'Amr:
The Prophet once came out and offered the funeral prayer for the martyrs of Uhud, and proceeded to the pulpit and said, "I shall be your predecessor and a witness on you, and I am really looking at my sacred Fount now, and no doubt, I have been given the keys of the treasures of the world. By Allah, I am not afraid that you will worship others along with Allah, but I am afraid that you will envy and fight one another for worldly fortunes."
حَدَّثَنِي سَعِيدُ بْنُ شُرَحْبِيلَ، حَدَّثَنَا لَيْثٌ، عَنْ يَزِيدَ، عَنْ أَبِي الْخَيْرِ، عَنْ عُقْبَةَ بْنِ عَامِرٍ، أَنَّ النَّبِيَّ ﷺ خَرَجَ يَوْمًا فَصَلَّى عَلَى أَهْلِ أُحُدٍ صَلاَتَهُ عَلَى الْمَيِّتِ، ثُمَّ انْصَرَفَ إِلَى الْمِنْبَرِ، فَقَالَ " إِنِّي فَرَطُكُمْ، وَأَنَا شَهِيدٌ عَلَيْكُمْ، إِنِّي وَاللَّهِ لأَنْظُرُ إِلَى حَوْضِي الآنَ، وَإِنِّي قَدْ أُعْطِيتُ خَزَائِنَ مَفَاتِيحِ الأَرْضِ، وَإِنِّي وَاللَّهِ مَا أَخَافُ بَعْدِي أَنْ تُشْرِكُوا، وَلَكِنْ أَخَافُ أَنْ تَنَافَسُوا فِيهَا ".
