Messenger of Allah, here is a point: If I happened to encounter a person amongst the infidels (in the battle). Then he narrated a hadith similar to the one transmitted by Laith.  

مسلم:٩٥cوَحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى أَخْبَرَنَا ابْنُ وَهْبٍ قَالَ أَخْبَرَنِي يُونُسُ عَنِ ابْنِ شِهَابٍ قَالَ حَدَّثَنِي عَطَاءُ بْنُ يَزِيدَ اللَّيْثِيُّ ثُمَّ الْجُنْدَعِيُّ أَنَّ عُبَيْدَ اللَّهِ بْنَ عَدِيِّ بْنِ الْخِيَارِ

أَخْبَرَهُ أَنَّ الْمِقْدَادَ بْنَ عَمْرِو بْنِ الأَسْوَدِ الْكِنْدِيَّ وَكَانَ حَلِيفًا لِبَنِي زُهْرَةَ وَكَانَ مِمَّنْ شَهِدَ بَدْرًا مَعَ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَالَ يَا رَسُولَ اللَّهِ أَرَأَيْتَ إِنْ لَقِيتُ رَجُلاً مِنَ الْكُفَّارِ ثُمَّ ذَكَرَ بِمِثْلِ حَدِيثِ اللَّيْثِ
