What is the ruling of Islamic law on the mourning of the deceased's family for forty days, during which they refrain from holding marriage ceremonies and celebrations? And is the distribution of Qur'anic booklets containing Surat Al-Kahf, Ya-Sin, and Al-Mulk an ongoing charity for the deceased? And how should the Qur'an be recited for the soul of the deceased? And is there anything mentioned in the Sunnah regarding the recitation of Surat Ya-Sin for the soul of the deceased?

Mourning a deceased person for 40 days and relatives abstaining from marriage celebrations is an innovation (bid‘ah). The legislated period of mourning is 3 days for a woman over a relative, and 4 months and 10 days for a wife over her husband. Donating copies of the Qur’an to the family of the deceased carries a reward. The reward for reciting the Qur’an reaches the deceased if the reciter intends it and dedicates the reward to them. Designating Surat Ya-Sin for the deceased is weak.
