"The Prophet took Abdur-Rahman bin Awf by the hand and went with him to his son Ibrahim. He found him in his last breaths, so he took him and put him on his lap and cried. Abdur-Rahman said to him: 'You cry? Didn't you prohibit (your followers) from crying?' He said: 'No. But I prohibited two foolish immoral voices: A voice during a calamity while clawing at one's face and tearing one's clothes, and Shaitan's scream.'" And there is more that is stated in the Hadith.
حَدَّثَنَا عَلِيُّ بْنُ خَشْرَمٍ، أَخْبَرَنَا عِيسَى بْنُ يُونُسَ، عَنِ ابْنِ أَبِي لَيْلَى، عَنْ عَطَاءٍ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ أَخَذَ النَّبِيُّ صلى الله عليه وسلم بِيَدِ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ فَانْطَلَقَ بِهِ إِلَى ابْنِهِ إِبْرَاهِيمَ فَوَجَدَهُ يَجُودُ بِنَفْسِهِ فَأَخَذَهُ النَّبِيُّ صلى الله عليه وسلم فَوَضَعَهُ فِي حِجْرِهِ فَبَكَى فَقَالَ لَهُ عَبْدُ الرَّحْمَنِ أَتَبْكِي أَوَلَمْ تَكُنْ نَهَيْتَ عَنِ الْبُكَاءِ قَالَ لاَ وَلَكِنْ نَهَيْتُ عَنْ صَوْتَيْنِ أَحْمَقَيْنِ فَاجِرَيْنِ صَوْتٍ عِنْدَ مُصِيبَةٍ خَمْشِ وُجُوهٍ وَشَقِّ جُيُوبٍ وَرَنَّةِ شَيْطَانٍ . وَفِي الْحَدِيثِ كَلاَمٌ أَكْثَرُ مِنْ هَذَا . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ .
