حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، وَأَنَا سَأَلْتُهُ، حَدَّثَنَا سُلَيْمَانُ بْنُ الْمُغِيرَةِ، حَدَّثَنَا ثَابِتٌ، عَنْ أَنَسٍ، قَالَ كُنَّا مَعَ عُمَرَ بَيْنَ مَكَّةَ وَالْمَدِينَةِ فَتَرَاءَيْنَا الْهِلَالَ وَكُنْتُ حَدِيدَ الْبَصَرِ فَرَأَيْتُهُ فَجَعَلْتُ أَقُولُ لِعُمَرَ أَمَا تَرَاهُ قَالَ سَأَرَاهُ وَأَنَا مُسْتَلْقٍ عَلَى فِرَاشِي ثُمَّ أَخَذَ يُحَدِّثُنَا عَنْ أَهْلِ بَدْرٍ قَالَ إِنْ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَيُرِينَا مَصَارِعَهُمْ بِالْأَمْسِ يَقُولُ هَذَا مَصْرَعُ فُلَانٍ غَدًا إِنْ شَاءَ اللَّهُ تَعَالَى وَهَذَا مَصْرَعُ فُلَانٍ غَدًا إِنْ شَاءَ اللَّهُ تَعَالَى قَالَ فَجَعَلُوا يُصْرَعُونَ عَلَيْهَا قَالَ قُلْتُ وَالَّذِي بَعَثَكَ بِالْحَقِّ مَا أَخْطَئُوا تِيكَ كَانُوا يُصْرَعُونَ عَلَيْهَا ثُمَّ أَمَرَ بِهِمْ فَطُرِحُوا فِي بِئْرٍ فَانْطَلَقَ إِلَيْهِمْ فَقَالَ يَا فُلَانُ يَا فُلَانُ هَلْ وَجَدْتُمْ مَا وَعَدَكُمْ اللَّهُ حَقًّا فَإِنِّي وَجَدْتُ مَا وَعَدَنِي اللَّهُ حَقًّا قَالَ عُمَرُ يَا رَسُولَ اللَّهِ أَتُكَلِّمُ قَوْمًا قَدْ جَيَّفُوا قَالَ مَا أَنْتُمْ بِأَسْمَعَ لِمَا أَقُولُ مِنْهُمْ وَلَكِنْ لَا يَسْتَطِيعُونَ أَنْ يُجِيبُوا‏.‏

It was narrated that Anas said: We were with 'Umar between Makkah and Madinah, and we looked for the new crescent moon. I was sharp sighted and I saw it, and I started saying to ‘Umar, Don't you see it? He said: I will see it when I am lying in my bed. Then he started telling us about the people of Badr. He said: the Messenger of Allah ﷺ was showing us the places where they would fall (in battle), saying: “This is where So and so will fall in battle tomorrow, if Allah wills; this is where So and so will fall in battle tomorrow, if Allah wills.” And they started to fall in those places, I said: By the One who sent you with the truth, they did not miss those places; they fell in those places. Then he ordered that they be thrown into a well, and he went to them and said: `O So and so, O So and so, did you find what Allah promised you to be true? For I found what Allah promised me to be true.` 'Umar said: O Messenger of Allah (ﷺ) , are you speaking to people who are now dead? He said: `You do not hear what I am saying any better than they do, but they cannot answer.` Grade: Sahih (Darussalam) [ Muslim (2873)] (Darussalam) Reference : Musnad Ahmad 182 In-book reference : Book 2, Hadith 99
