عَنْ نُعَيْمِ بْنِ هَمَّارٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَجُلًا سَأَلَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَيُّ الشُّهَدَاءِ أَفْضَلُ قَالَ الَّذِينَ إِنْ يُلْقَوْا فِي الصَّفِّ يَلْفِتُونَ وُجُوهَهُمْ حَتَّى يُقْتَلُوا أُولَئِكَ يَنْطَلِقُونَ فِي الْغُرَفِ الْعُلَى مِنَ الْجَنَّةِ وَيَضْحَكُ إِلَيْهِمْ رَبُّهُمْ وَإِذَا ضَحِكَ رَبُّكَ إِلَى عَبْدٍ فِي الدُّنْيَا فَلَا حِسَابَ عَلَيْهِ
It is narrated from Sayyiduna Nu’aim bin Hammar (may Allah be pleased with him) that a man asked the Noble Prophet (peace and blessings be upon him): "Which martyrs are the most virtuous?" The Prophet (peace and blessings be upon him) replied: "They are those people who, when facing the enemy in the ranks, turn their faces towards them until they are martyred. These are the people who walk in the lofty chambers of Paradise, and their Lord smiles at them. And when your Lord smiles at someone in this world, there is no reckoning for him."
