O Abu Jahl b. Hisham, O Umayya b. Khalaf, O Utba b. Rab'ila, O Shaiba b. Rabi'a, have you not found what your Lord had promised with you to be correct? As for me, I have found the promises of my Lord to be (perfectly) correct. Umar listened to the words of Allah's Apostle ﷺ and said: Messenger of Allah, how do they listen and respond to you? They are dead and their bodies have decayed. Thereupon he (the Holy Prophet) said: By Him in Whose Hand is my life, what I am saying to them, even you cannot hear more distinctly than they, but they lack the power to reply. Then'he commanded that they should be buried in the well of Badr. (Using translation from Muslim 2874)
أَنَّ رَسُولَ اللهِ ﷺ تَرَكَ قَتْلَى بَدْرٍ ثَلَاثَةَ أَيَّامٍ حَتَّى جَيَّفُوا ثُمَّ أَتَاهُمْ فَقَامَ عَلَيْهِمْ فَقَالَ يَا أُمَيَّةُ بْنَ خَلَفٍ يَا أَبَا جَهْلِ بْنَ هِشَامٍ يَا عُتْبَةُ بْنَ رَبِيعَةَ يَا شَيْبَةُ بْنَ رَبِيعَةَ هَلْ وَجَدْتُمْ مَا وَعَدَكُمْ رَبُّكُمْ حَقًّا؟ فَإِنِّي قَدْ وَجَدْتُ مَا وَعَدَنِي رَبِّي حَقًّا قَالَ فَسَمِعَ عُمَرُ صَوْتَهُ فَقَالَ يَا رَسُولَ اللهِ أَتُنَادِيهِمْبَعْدَ ثَلَاثٍ وَهَلْ يَسْمَعُونَ؟ يَقُولُ اللهُ ﷻ {إِنَّكَ لَا تُسْمِعُ الْمَوْتَى} [النمل 80] ؟ فَقَالَ وَالَّذِي نَفْسِي بِيَدِهِ مَا أَنْتُمْ بِأَسْمَعَ مِنْهُمْ وَلَكِنَّهُمْ لَا يَسْتَطِيعُونَ أَنْ يُجِيبُوا
