Allah Most High, says, {After payment of legacies and debts: so that no loss is caused (to any).} (An-Nisa': 12)

This means that when someone brings loss to heirs by claiming that he is indebted to such and such.

Allah the Almighty says, {Thus is it ordained by Allah, and Allah is All-Knowing, Most Forbearing. Those are limits set by Allah:

those who obey Allah and his Messenger will be admitted to gardens with rivers flowing beneath, to abide therein (forever) and that will be the supreme achievement. But those who disobey Allah and his Messenger and transgress his limits will be admitted to a fire, to abide therein: and they shall have a humiliating punishment.} (An-Nisa': 12-14)

The reward and the punishment mentioned in the aforementioned Ayat concerns those who deal with the inheritance. Abu Hurairah related that Prophet (pbuh) said, "A man or a woman work abiding by Allah's commandments for sixty years until the death comes to them.

Then they bring loss to the bequest and thereby they enter the hellfire". Then Abu Hurairah reads, Allah's saying: {After payment of legacies and debts: so that no loss is caused (to any one)}" 1

"Whoever prevents his heirs from receiving their inheritance, Allah will prevent his inheriting Paradise.”2

"Allah has given every one his right. Thus there is no bequest for an heir.” 3
