Hadith.5429 - It is narrated from Ahmad ibn Muhammad ibn Isa from Ahmad ibn Ishaq that he wrote to Abu Al-Hasan (as), informing him: "Durrah bint Muqatil has passed away and left behind an estate consisting of portions in a certain place. She bequeathed more than one-third of her estate to our master, and we are her executors. We wished to inform our master about this matter. If you command us to carry out the will as it is, we will do so. But if you command otherwise, we will adhere to your instruction in all that you command us, God willing." So Abu Al-Hasan (as) replied in his own handwriting: "She is entitled to only one-third of her estate. However, if you, as the heirs, choose to be generous, it is permissible for you, God willing."

Hadith.5430 - Ṣafwan narrated from Murazim from some of our companions regarding a man who gives something from his wealth during his illness. Imam (as) said: "If he gives it explicitly (clearly handing it over), then it is valid. But if he bequeaths it (without handing it over), then it must be from one-third of his estate." Hadith.5467 - And the confirmation of this is what Ṣafwan narrated from Murazim regarding a man who gives something from his wealth during his illness. Imm (as) said: "If he clearly transfers it (during his lifetime), then it is valid. However, if he bequeaths it (for after his death), then it is only from one-third of his wealth."

Hadith.5431 - Ali ibn Ibrahim ibn Hashim narrated from Ali ibn Ishaq, from Al-Hasan ibn Hazim Al-Kalbi, the nephew of Hisham ibn Salim, from Sulayman ibn Ja'far (who was not from the Ja'fari lineage), from Abu Abdullah (as), who said: The Messenger of Allah (swt) (peace be upon him and his family) said: "Whoever does not make a proper will at the time of death, it is a deficiency in his dignity and intellect." It was asked: "O' Messenger of Allah (swt), how does a dying person make a will?" Prophet (sw) replied: "When his death approaches and people gather around him, he should say: "O' Allah (swt), Creator of the heavens and the earth, Knower of the unseen and the seen, the Most Merciful, the Most Compassionate. O' Allah (swt), I make a covenant with You (swt) in this worldly life that I bear witness there is no God but You (swt), alone with no partner. And that Muhammad (sw) is Your (swt) servant and Your Messenger (sw). Paradise is true, Hellfire is true, resurrection is true, reckoning is true, the path (Sirat) is true, divine decree and the scale (Mizan) are true. Indeed, the religion is as You (swt) have described, Islam is as You (swt) have legislated, the word is as You (swt) have conveyed, and the Qur'an is as You (swt) have revealed. And You (swt) are Allah (swt), the True and Manifest. May Allah (swt) reward Muhammad (sw) on our behalf with the best reward, and may Allah (swt) send peace upon Muhammad (sw) and the family of Muhammad (sw). O' Allah (swt), You (swt) are my refuge in my hardship, my companion in my difficulty, and the guardian of my blessings. My God (swt) and the God (swt) of my forefathers, do not leave me to myself for the blink of an eye, for if You (swt) abandon me to myself, I will be closer to evil and farther from good. Bring comfort to my loneliness in the grave, and grant me a written covenant on the Day I meet You (swt). Then he should state his wishes (in his will). The confirmation of this will is found in the Quran, in the chapter where Maryam {s.a} is mentioned, in the words of Allah (swt), the Almighty and Majestic: "They do not possess [the right of] intercession except for those who have taken a covenant with the Most Merciful." (Surah Maryam 19:87) This is the covenant of the dying person, and making a will is an obligation upon every Muslim. It is a duty to preserve this will and to teach it to others. Commander of the Faithful Imam Ali ibn Abi Talib (as) said: "The Messenger of Allah (swt), peace be upon him and his family, taught it to me." And the Messenger of Allah (swt), said: "Jibril (as) taught it to me (from Allah (swt))."
