عَنْ عُقْبَةَ بْنِ عَامِرٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ صَلَّى عَلَى قَتْلَى أُحُدٍ بَعْدَ ثَمَانِ سِنِينَ كَالْمُوَدِّعِ لِلْأَحْيَاءِ وَالْأَمْوَاتِ ثُمَّ طَلَعَ الْمِنْبَرَ فَقَالَ إِنِّي فَرَطُكُمْ وَأَنَا عَلَيْكُمْ شَهِيدٌ وَإِنَّ مَوْعِدَكُمُ الْحَوْضُ وَإِنِّي لَأَنْظُرُ إِلَيْهِ وَلَسْتُ أَخْشَى عَلَيْكُمْ أَنْ تُشْرِكُوا أَوْ قَالَ تَكْفُرُوا وَلَكِنِ الدُّنْيَا أَنْ تَتَنَافَسُوا فِيهَا
It is narrated from Sayyiduna Uqbah bin Amir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) offered the funeral prayer for the martyrs of the Battle of Uhud eight years later. It seemed as if he was bidding farewell to the living and the dead. Then the Prophet (peace and blessings be upon him) ascended the pulpit and said: I will precede you and will bear witness for you. Surely, your promised place is the Pond, and I am looking at it right now. I do not fear shirk for you, but I fear the world, that you may become engrossed in it. In one narration, the word "kufr" is mentioned instead of "shirk".
