Hadith.5559 - Muhammad ibn Abi Umayr narrated from Hammad ibn Uthman from Abu Abdullah (as), who said: 'A man bequeathed thirty dinars to the descendants of Sayyidah Fatimah {s.a}, peace be upon her. The man brought the money to Abu Abdullah (as), who said: "Give it to such-and-such an elder from the descendants of Sayyidah Fatimah {s.a}, peace be upon her," and that man was poor and struggling to provide for his family. The man responded: "But the deceased specifically bequeathed it to the descendants of Sayyidah Fatimah {s.a}." Abu Abdullah (as) replied: "It will not have the same impact on the descendants of Sayyidah Fatimah {s.a} in general, but it will have a meaningful impact on this man, for he has a family to support."

Hadith.5560 - Ibn Faddal narrated from Ali ibn Uqbah from Burayd ibn Mu'awiyah from Abu Abdullah (as), who said: I said to Imam (as): "A man appointed me as his executor, and I asked him to appoint a relative of his to share the responsibility with me, and he agreed. The one who appointed me mentioned that the co-executor owed him one hundred and fifty dirhams and that he had a silver cup as collateral for this debt. When the man passed away, the co-executor began to claim that he was owed sacks of wheat instead." Abu Abdullah (as), said: "If he brings proof, then his claim is valid; otherwise, he has no right to anything." I asked: "Is it permissible for him to take anything from what is in his possession?" Imam (as) replied: "It is not permissible for him." I then asked: "What if someone wrongfully took his wealth, and he found the opportunity to take back from that person's wealth the equivalent of what was taken from him - would that be permissible?" Imam (as) replied: "This is not the same as that."
