Is there an effect indicating that death permeates the body 40 days before one's appointed time, and does the deceased enter Paradise through the gate of Ar-Rayyan during Ramadan? What are the deeds by which one can honor their mother after her death, and does she receive the reward of Qur'an recitation and Dhikr? Is there a Hadith that states the deceased becomes aware of the joyful news of their relatives? And what is the way to overcome a state of despair after losing one's mother?

There is no Shari (Islamic legal) evidence for death spreading through the body forty days before demise, nor for any special virtue in dying during Ramadan. Entering Paradise through the gate of Ar-Rayyan is indeed specific to those who fast, especially those who frequently observe supererogatory fasts. The preponderant opinion is that the reward for reciting the Quran and engaging in dhikr (remembrance of Allah) does not reach the deceased, as there is no transmission of this from the Prophet, peace and blessings be upon him, or his Companions. As for the deceased being aware of the news of the living, this has been established by narrations, where they recognize each other, inquire about the affairs of their families, have the deeds of the living presented to them, and greet those who visit them. However, souls do not return to their families' homes after death. Whoever loses a loved one should be patient and say, "Indeed we belong to Allah, and indeed to Him we will return," and ask Allah to cause them to die upon righteous deeds so that they may reunite in the Paradise of contentment.
