1. For your deceased ones, First forgive them sincerely; It will seem strange to you, but Imam Mohammad Baqir (a.s.) says that many parents are considered as rejected (aakh) because of not fulfilling the rights of their children (manazil al-akhirah), so it is possible that your parents have violated your rights. (O Allah, even if I am pleased with them, do not make it difficult for them because of me) and remember them in good words, narrate the incidents of their good deeds and refrain from narrating those incidents when they commit any mistake,cruelty, abuse.

5. Be sure to recite Namaz-e- Wahshat e qabr or recite Nawafil whenever you desire, or offer a prayer with the intention of offering one of their Qaza prayers. Imam Jafar e Sadiq (a.s.) says that sometimes the dead person is caught in punishment due to some sin or suddenly his punishment is removed, he asks how this happened and he gets the answer that so-and-so servant has prayed for you. It happened because of that. Imam says that the dead person is happy like you are happy when you get a gift. (Tohfatul momineen )

7- Every night, if possible, or every Friday night, give charity for their reward. Imam Jafar Sadiq (a.s.) says that the deceased come to their homes and cry, “Oh, our family, give charity for us, even if it is a loaf of bread.” Even if it’s a piece. (Mafatih al-Jinan)
8- The intention of charity is very good, O Allah, one part of this charity is for the health and safety of the Imam e zamana, one part is for my deceased, and also all the deceased believers, and one part is for the health and safety of all of us.
9- If you go to the grave, perform the deeds of the cemetery. Reciting Surah Qadr seven times by burying your fingers in the grave, Imam Reza (A.S.) used to say that by doing this, an angel will continue to do good deeds for the dead person until the Day of Resurrection, and the reward will continue to be given to the dead person. ( Manazil e Akhirat )

14. All Thursday; 10th day, 40th day, you cook food for nazr o niaz, you also invite the poor people of the area or deliver food to them so that there is a great reward. Imam Hasan (a.s.) says that the worst invitation is that in which the rich are invited but the poor are not invited.
( Guftaar e Masoomeen)
15- Perform Majlis e Aza, And the Quran Recitation. A woman saw her husband in a dream that he was thanking that he was imprisoned in the chains of fire, but his chains came off due to the recitation of the Quran.
