The Messenger of Allah ﷺ prohibited us to wail.  

إِنَّ رَسُولَ اللَّهِ ﷺ نَهَانَا عَنِ النِّيَاحَةِ  

The Messenger of Allah ﷺ cursed the wailing woman and the woman who listens to her.  

لَعَنَ رَسُولُ اللَّهِ ﷺ النَّائِحَةَ وَالْمُسْتَمِعَةَ  

The Messenger of Allah ﷺ as saying: The dead is punished because of his family's weeping for him. When this was mentioned to 'Aishah, she said: Ibn 'Umar forgot and made a mistake. The Prophet ﷺ passed by grave and he said: The man in the grave is being punished while his family is weeping for him. She then recited: "No bearer of burdens can bear the burden of another." The narrator Abu Mu'awiyyah said: (The Prophet passed) by the grave of a Jew.  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ الْمَيِّتَ لَيُعَذَّبُ بِبُكَاءِ أَهْلِهِ عَلَيْهِ فَذُكِرَ ذَلِكَ لِعَائِشَةَ فَقَالَتْ وَهِلَ تَعْنِي ابْنَ عُمَرَ إِنَّمَا مَرَّ النَّبِيُّ ﷺ عَلَى قَبْرٍ فَقَالَ إِنَّ صَاحِبَ هَذَا لَيُعَذَّبُ وَأَهْلُهُ يَبْكُونَ عَلَيْهِ ثُمَّ قَرَأَتْ { وَلاَ تَزِرُ وَازِرَةٌ وِزْرَ أُخْرَى } قَالَ عَنْ أَبِي مُعَاوِيَةَ عَلَى قَبْرِ يَهُودِيٍّ  

I entered upon AbuMusa while he was at the point of death. His wife began to weep or was going to weep. AbuMusa said to her: Did you not hear what the Messenger of Allah ﷺ said? She said: Yes. The narrator said: She then kept silence. When AbuMusa died, Yazid said: I met the woman and asked her: What did AbuMusa mean when he said to you: Did you not hear what the Messenger of Allah ﷺ and the you kept silence? She replied: The Messenger of Allah ﷺ said: He who shaves (his head), shouts and tears his clothing does not belong to us.  

دَخَلْتُ عَلَى أَبِي مُوسَى وَهُوَ ثَقِيلٌ فَذَهَبَتِ امْرَأَتُهُ لِتَبْكِي أَوْ تَهُمَّ بِهِ فَقَالَ لَهَا أَبُو مُوسَى أَمَا سَمِعْتِ مَا قَالَ رَسُولُ اللَّهِ ﷺ قَالَتْ بَلَى قَالَ فَسَكَتَتْ فَلَمَّا مَاتَ أَبُو مُوسَى قَالَ يَزِيدُ لَقِيتُ الْمَرْأَةَ فَقُلْتُ لَهَا مَا قَوْلُ أَبِي مُوسَى لَكِ أَمَا سَمِعْتِ مَا قَالَ رَسُولُ اللَّهِ ﷺ ثُمَّ سَكَتِّ قَالَتْ قَالَ رَسُولُ اللَّهِ ﷺ لَيْسَ مِنَّا مَنْ حَلَقَ وَمَنْ سَلَقَ وَمَنْ خَرَقَ  

One of the oaths which the Messenger of Allah ﷺ received from us about the virtue was that we would not disobey him in it (virtue): that we would not scratch the face, nor wail, nor tear the front of the garments nor dishevel the hair.  

كَانَ فِيمَا أَخَذَ عَلَيْنَا رَسُولُ اللَّهِ ﷺ فِي الْمَعْرُوفِ الَّذِي أَخَذَ عَلَيْنَا أَنْ لاَ نَعْصِيَهُ فِيهِ أَنْ لاَ نَخْمِشَ وَجْهًا وَلاَ نَدْعُوَ وَيْلاً وَلاَ نَشُقَّ جَيْبًا وَأَنْ لاَ نَنْشُرَ شَعْرًا
