وَعَنْهُ قَالَ: انْطَلَقَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَأَصْحَابُهُ حَتَّى سَبَقُوا الْمُشْرِكِينَ إِلَى بَدْرٍ وَجَاءَ الْمُشْرِكُونَ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «قُومُوا إِلَى جَنَّةٍ عَرْضُهَا السَّمَاوَاتُ وَالْأَرْضُ» . قَالَ عُمَيْرُ بْنُ الْحُمَامِ: بَخْ بَخْ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: " مَا يَحْمِلُكَ عَلَى قَوْلِكَ: بَخْ بَخْ؟ " قَالَ: لَا وَاللَّهِ يَا رَسُولَ اللَّهِ إِلَّا رَجَاءَ أَنْ أَكُونَ مِنْ أَهْلِهَا قَالَ: «فَإِنَّكَ مِنْ أَهْلِهَا» قَالَ: فَأَخْرَجَ تَمَرَاتٍ مِنْ قَرْنِهِ فَجَعَلَ يَأْكُلُ مِنْهُنَّ ثُمَّ قَالَ: لَئِنْ أَنَا حَيِيتُ حَتَّى آكل تمراتي إِنَّهَا الْحَيَاة طَوِيلَةٌ قَالَ: فَرَمَى بِمَا كَانَ مَعَهُ مِنَ التَّمْرِ ثُمَّ قَاتَلَهُمْ حَتَّى قُتِلَ. رَوَاهُ مُسْلِمٌ

He told that God’s Messenger and his companions went off and reached Badr before the polytheists, and when the polytheists arrived he said, “Rise to go to a garden whose breadth is as great as the heavens and the earth.” ‘Umair b. al-Humam thereupon said, “Bravo, bravo!” and when God’s Messenger asked him what had made him say that, he replied, “Nothing, I swear by God, Messenger of God, but a hope that I might be among its inhabitants.” He told him that he would be among them. He then took some dates out of his quiver and began to eat them, but after a little said, “If I live till I eat my dates it will mean a long life.” So he threw away the dates he had and then fought with the enemy till he was killed. Muslim transmitted it.
