Musannaf Ibn Abi Shaybah

Hazrat Abu Al-Bakhtari says that providing food on someone's death and wailing are both acts of ignorance.

Hazrat Saeed bin Jubair states that there are three practices of ignorance: for a non-related woman to spend the night at the house of those afflicted by calamity, wailing, and slaughtering an animal at the time of calamity (for eating).

Hazrat Qais narrates that Hazrat Umar bin Abdul Aziz used to prohibit gatherings at the house of the deceased and used to say that on one hand, they are suffering from grief and on the other hand, they have to bear a penalty.

Hazrat Talha narrates that Hazrat Jarir came to Hazrat Umar and asked, "Is wailing performed over the deceased among you?" He replied, "No." Hazrat Jarir then asked, "Do women gather at the place of the deceased among you and is food served?" He replied, "Yes." Hazrat Jarir said, "This itself is wailing."
