An emotional sermon by Ali ibn Abi Talib (Radi Allah anhu) about Death.

Amir al-Mu'mineen 'Ali (Radi Allah anhu) paid attention to making use of different occasions to exhort and remind the people; he did not limit it to Friday sermons only. When he walked with the funeral procession and heard the voices of the bereaved family raised in weeping as the body was placed in the niche in the grave, he would say:

"Why are you weeping? By Allah, if they could see what your deceased one is seeing, they would be distracted from their deceased one by what they see. Death will come back again and again, until none of them is left. So fear Allah, O slaves of Allah, and strive hard in righteous deeds. Hasten to do good deeds before death, the destroyer of pleasures, comes. The pleasures of this world will not last, and you cannot feel secure against the calamities of this world, for it is fleeting and deceitful and cannot be relied on. Learn the lessons, O slaves of Allah, and heed the exhortation, for soon you will die and will be buried. Soon the Trumpet will be blown, and the occupants of the graves will be raised and driven to the arena of gathering for the Reckoning. Everything is under the control of the Almighty. Every person will have an angel to drive him and an angel to bear witness to his deeds.
“And the earth will shine with the light of its Lord [Allah], when He will come to judge among men, and the Book will he placed [open], and the Prophets and the witnesses will be brought forward, and it will be judged between them with truth, and they will not be wronged.) (Qur'an 39: 69) "
