Prompt your departed ones to say: ‘There is no god except Allah’ for it erases the sins. So they asked: O Messenger of Allah (s.a.w.s.), what if one recites this when one is healthy (alive)? The Holy Prophet (s.a.w.s.) replied, “This (utterance) destroys the sins and finishes them off in any condition. Indeed “There is no God except Allah” is a friend and helper of man in life in eath and in raising after death. The Messenger of Allah (s.a.w.s.) also said: Jibraeel said: O Muhammad! You shall see them when they are raised with shining countenances those who used to chant: There is no God except Allah and Allah is the greatest.” And those shall be black faced who used to say: “Woe be to you, you are ruined!”

Sawab al-A`amal, Page 28

“One night I left the house and suddenly saw the Prophet of Allah (a.s) walking all alone. I thought maybe he did not want anyone to walk with him, so in the moonlight I started walking very slowly behind him. The Prophet (a.s) became aware that I was behind him and inquired: “Who is it?” I answered him as so “May I be your devoted servant. I am Abuzar.” The Prophet (a.s) said: “O' Abuzar! Come along with me.” So I walked with him for one hour. Then the Prophet (a.s) remarked: “On Judgment Day the money-makers will be in the minority except those to whom Allah grants goodness and they give charity in the world to the left and the right sides, and in front of and in back, and use it to do good deeds.” Then Abuzar said: “I walked another hour with the Prophet (a.s) and then he stated: “Sit down here!” Then he made me sit down on a stony piece of land surrounded by mountains and hills. He stated: “Sit here until I return.” The Prophet (a.s) set out for a place by the name of Harra. He set out and I could no longer see him. Later, as the Prophet (a.s) was approaching me I heard him saying: “... and what if he has committed adultery? And what if he has stolen something?” As the Prophet (a.s) approached me, I impatiently asked him: “O' Prophet of Allah! May Allah make me your devoted servant! Who were you talking with over there in Harra? I heard someone answering your questions.” The Prophet (a.s) said: “(The angel) Gabriel showed himself to me at Harra and said: Give good news to your nation: whoever dies and has not associated any partners with Allah (the Almighty) will enter Heaven. I said: O' Gabriel! And is that so even if he has committed adultery? And is that so even if he has stolen something? Gabriel answered in the positive. Again I asked: And even if he has committed adultery? And is that so even if he has stolen something? Gabriel answered: Yes, even if he has drunk an intoxicating drink.”

Therefore remember what will make it easier for you to attain this knowledge, and prepares you to retain it.” Then the Imam (a.s) added: “Unity implies that you do not deem permissible with Allah what you deem permissible with yourself. And justice implies that you do not associate with Allah what He has reproached you for.”
