حَدَّثَنَا أَحْمَدُ بْنُ عَمْرِو بْنِ السَّرْحِ، حَدَّثَنَا ابْنُ وَهْبٍ، عَنْ حَيْوَةَ بْنِ شُرَيْحٍ، وَابْنِ، لَهِيعَةَ عَنْ يَزِيدَ بْنِ أَبِي حَبِيبٍ، عَنْ أَسْلَمَ أَبِي عِمْرَانَ، قَالَ ‏:‏ غَزَوْنَا مِنَ الْمَدِينَةِ نُرِيدُ الْقُسْطَنْطِينِيَّةَ، وَعَلَى الْجَمَاعَةِ عَبْدُ الرَّحْمَنِ بْنُ خَالِدِ بْنِ الْوَلِيدِ وَالرُّومُ مُلْصِقُو ظُهُورِهِمْ بِحَائِطِ الْمَدِينَةِ، فَحَمَلَ رَجُلٌ عَلَى الْعَدُوِّ فَقَالَ النَّاسُ ‏:‏ مَهْ، مَهْ، لاَ إِلَهَ إِلاَّ اللَّهُ، يُلْقِي بِيَدَيْهِ إِلَى التَّهْلُكَةِ ‏.‏ فَقَالَ أَبُو أَيُّوبَ ‏:‏ إِنَّمَا نَزَلَتْ هَذِهِ الآيَةُ فِينَا مَعْشَرَ الأَنْصَارِ لَمَّا نَصَرَ اللَّهُ نَبِيَّهُ وَأَظْهَرَ الإِسْلاَمَ، قُلْنَا ‏:‏ هَلُمَّ نُقِيمُ فِي أَمْوَالِنَا وَنُصْلِحُهَا، فَأَنْزَلَ اللَّهُ تَعَالَى ‏‏{‏ وَأَنْفِقُوا فِي سَبِيلِ اللَّهِ وَلاَ تُلْقُوا بِأَيْدِيكُمْ إِلَى التَّهْلُكَةِ ‏}‏ فَالإِلْقَاءُ بِالأَيْدِي إِلَى التَّهْلُكَةِ أَنْ نُقِيمَ فِي أَمْوَالِنَا وَنُصْلِحَهَا وَنَدَعَ الْجِهَادَ ‏.‏ قَالَ أَبُو عِمْرَانَ ‏:‏ فَلَمْ يَزَلْ أَبُو أَيُّوبَ يُجَاهِدُ فِي سَبِيلِ اللَّهِ حَتَّى دُفِنَ
Translation
Narrated AbuAyyub

Aslam Abu Imran said: We set out from Medina intending to go to Constantinople, and the commander over the group was Abdur-Rahman ibn Khalid ibn al-Walid. The Byzantines had their backs pressed against the walls of the city. A man charged against the enemy, whereupon the people said: 'Hold, hold! There is no god but Allah; he is casting himself into destruction.' Abu Ayyub said: 'This verse was revealed concerning us, the group of the Ansar: when Allah aided His Prophet and made Islam prevail, we said: Let us stay in our wealth and improve it. Then Allah, the Exalted, revealed:

And spend in the way of Allah and do not throw yourselves into destruction with your own hands
Casting oneself into destruction means staying in our wealth and improving it while abandoning jihad.' Abu Imran said: 'Abu Ayyub continued to strive in the way of Allah until he was buried [there].'
