It was narrated that Ibn 'Abbas said:"The Messenger of Allah said: 'Whoever is killed in the blind or by something thrown, while between them is a rock, a wipe, or a stick, then the blood money of be paid for him is the blood money for accidental killing. Whoever kills deliberately, then retaliation is upon him, and whoever tries to prevent that, upon him is the curse of Allah, the Angels, and all the people, and neither Sarf nor Adl will be accepted from him."
أَخْبَرَنَا هِلاَلُ بْنُ الْعَلاَءِ بْنِ هِلاَلٍ، قَالَ حَدَّثَنَا سَعِيدُ بْنُ سُلَيْمَانَ، قَالَ أَنْبَأَنَا سُلَيْمَانُ بْنُ كَثِيرٍ، قَالَ حَدَّثَنَا عَمْرُو بْنُ دِينَارٍ، عَنْ طَاوُسٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ قُتِلَ فِي عِمِّيَا أَوْ رِمِّيَا تَكُونُ بَيْنَهُمْ بِحَجَرٍ أَوْ سَوْطٍ أَوْ بِعَصًا فَعَقْلُهُ عَقْلُ خَطَإٍ وَمَنْ قَتَلَ عَمْدًا فَقَوَدُ يَدِهِ فَمَنْ حَالَ بَيْنَهُ وَبَيْنَهُ فَعَلَيْهِ لَعْنَةُ اللَّهِ وَالْمَلاَئِكَةِ وَالنَّاسِ أَجْمَعِينَ لاَ يُقْبَلُ مِنْهُ صَرْفٌ وَلاَ عَدْلٌ " .
