Narrated Abu Malik al-Ash'ari reported God’s messenger as saying, "Among my people there are four characteristics belonging to the pre-Islamic period which they do not abandon:
boasting of high rank, reviling other people’s genealogies, seeking rain by the stars, and wailing." And he said, "If the wailing-woman does not repent before she dies, she will be made to stand on the day of resurrection wearing a garment of pitch and a chemise of mange.”
Abu Burda said that Abu Musa al-Ash'ari fainted and his wife Umm ‘Abdallah began to shout with a piercing cry. He then came round, and asking her if she was quite ignorant, he told her that God’s messenger had said, "I have no connection with one who shaves, shouts and tears his clothing."
Anas told that when the Prophet came upon a woman weeping at a grave he said, "Fear God and show endurance.” She, not recognising him, replied, "Go away, for you have not been afflicted as I have.” She was told that he was the Prophet, so she went to his door, and finding no doorkeepers there she said, "I did not recognise you." He replied, "Endurance is shown only at the first blow.”
'Abdallah b. Mas'ud reported God’s messenger as saying, "He who beats the cheeks, tears the front of the garments, and cries out as people did in pre-Islamic times, does not belong to us."
