Hadith.5552 - Ibn Abi Umayr narrated from Ammar ibn Marwan, who said: "I said to Abu Abdullah (as): 'My father was on his deathbed, and I said to him, "Make a will." He (my father) said, "This is my son," referring to Umar, "whatever he does is valid."' Abu Abdullah (as), said: "Your father has indeed made a will and done so concisely." I said: 'He also instructed and willed to give you such and such.' Imam (as) said: "Approve it." I said: 'He made a bequest to free a believing and knowledgeable soul, but when we emancipated her, it became evident that she was not of proper lineage.' Imam (as) said: "It has fulfilled his obligation. The example of this is like a man who buys a sacrificial animal thinking it is fat, but then finds it to be thin. It still suffices for him."

Hadith.5553 - Abdullah ibn Ja'far Al-Himyari narrated from Al-Hasan ibn Malik, who said: 'I wrote to Imam (as) - meaning Imam Ali ibn Muhammad Al-Hadi (as) - about a man who died and had, during his lifetime, given everything he owned to you. He had no children at the time, but later he had a child. His total wealth amounted to three thousand dirhams, and I have sent you one thousand dirhams. If you see fit, may Allah (swt) make me your sacrifice, kindly inform me of your opinion so I may act accordingly.' Imam (as) wrote in response: "Release it to them (the surviving children)."

Hadith.5554 - Muhammad ibn Ya'qub Al-Kulayni, may Allah (swt) be pleased with him, narrated from Muhammad ibn Yahya from Muhammad ibn Isa ibn Ubayd, who said: "I wrote to Imam Ali ibn Muhammad Al-Hadi (as) asking about a man who allocated something from his wealth for you - may Allah (swt) make me your sacrifice - but later found himself in need of it. Should he take it back for himself or still send it to you?" Imam (as) replied: "He has the choice in this matter as long as he has not handed it over. And if it were to reach us, we would consider supporting him with it since he is now in need." He (Muhammad ibn Isa) further wrote to Imam (as), asking about a man who made a will, designating something specific from his wealth for you - may Allah (swt) make me your sacrifice - and also bequeathed portions to his relatives from his father's and mother's side. Then he altered the will, depriving those he had initially granted and granting to those he had initially deprived. Is this permissible for him? Imam (as) wrote in response: "He has full discretion in all of this until death approaches him."
