Surat Saad (The letter Saad) - ص

إِذْ عُرِضَ عَلَيْهِ بِٱلْعَشِىِّ ٱلصَّٰفِنَٰتُ ٱلْجِيَادُ ﴿٣١﴾ فَقَالَ إِنِّىٓ أَحْبَبْتُ حُبَّ ٱلْخَيْرِ عَن ذِكْرِ رَبِّى حَتَّىٰ تَوَارَتْ بِٱلْحِجَابِ﴿٣٢﴾ رُدُّوهَا عَلَىَّ فَطَفِقَ مَسْحًۢا بِٱلسُّوقِ وَٱلْأَعْنَاقِ﴿٣٣﴾

When there were brought to him in the evening (horses) still when standing, swift when running-- Then he said: Surely I preferred the good things to the remembrance of my Lord-- until the sun set and time for Asr prayer was over, (he said): Bring them back to me; so he began to slash (their) legs and necks.
