Wailing refers to mourning in a loud voice and crying in a high pitch, which was prohibited by the Prophet, peace be upon him. Abu Malik alAsh’ari reported that the Prophet, peace be upon him, said: “Four practices of the pre-Islamic days of Ignorance will continue to be practiced by my ummah: taking pride in one’s parentage, giving a person a father other than his own genealogical father, believing that rain is caused by some stars, and wailing over the dead.” He further said: “A (professional) mourner,Â unless she repents before her death, will be raised on the Day of Judgement wearing a garment of tar and an armour of blistering puss.” This is narrated by Ahmad and Muslim.
Umm ‘Atiyyah reports: “The Messenger of Allah made us pledge that we will not wail over (the dead)” (Bukhari and Muslim). Al-Bazzar has transmitted, through a sound chain of authorities the report that the Prophet, peace be upon him, said: “Two sounds are accursed in this world and in the hereafter: the sound of wind instruments (to celebrate) good fortune, and of moaning aloud when afflicted with a misfortune.”
Abu Musa is reported to have said: ‘I declare my disavowal of all that Allah’s Messenger disavowed. The Messenger of Allah disavowed publicly a woman who mourns loudly, one who shaves her head, and one who tears her clothes in mourning” (Bukhari and Muslim).
Ahmad narrates from Anas that he said: “The Prophet, peace be upon him, made the women pledge, while giving their allegiance to him, not to mourn loudly for the dead. Thereupon they asked him, ‘O Messenger of Allah, some women helped us (in mourning our dead) during the pre-Islamic days. Should we (also in return) help them (in mourning their dead) now that we are Muslims?’ He replied: ‘There is no such thing in Islam (i.e., helping each other to mourn the dead loudly)’.”
