Three days, and iddah for a widow
awaitingAdminReview
happens
Mourning lasts three days, when relatives and neighbours bring food to the family. A widow observes a longer waiting period of four months and ten days. Prayers and charity continue on behalf of the dead.
why
Grief is natural, and the Prophet ﷺ wept for his son; but mourning should not turn into despair, and patience is rewarded.
origins
Three days and the widow's period: Bukhari 1280 and Qur'an 2:234. Gatherings on the 3rd, 7th or 40th day are cultural customs in many regions; scholars differ on them.
