فِقهُ الوَصِيَّة — الوَصِيَّةُ فِي الشَّرِيعَةِ الإِسلَامِيَّة: بَيَانُ مَا يَجُوزُ لِلمُسلِمِ أَن يُوصِيَ بِهِ مِن مَالِهِ
Fiqh al-Wasiyyah (فِقهُ الوَصِيَّة — Jurisprudence of the Will/Bequest; *wasiyyah*: from *w-s-y*: to connect, to charge, to recommend; wasiyyah = a bequest — a disposition of property to take effect after death; also: wasiyyah as general 'counsel' or 'recommendation' [from the same root]; the testator [musi] and the legatee [musa lahu]; the basic definition: the wasiyyah is a statement by a person with legal capacity directing that a portion of their property is to go to a specified beneficiary after their death; it takes effect after death [unlike a gift, which takes effect immediately]; the Quranic basis: [1] 2:180: 'kutiba 'alaykum idha hadara ahadakum al-mawtu in taraka khayran al-wasiyyatu li-l-walidayni wa-l-aqrabina bi-l-ma'rufi haqqan 'ala al-muttaqin' [Prescribed for you when death approaches one of you — if he leaves wealth — is that he make a bequest [wasiyyah] for parents and near relatives, according to what is right — a duty upon the God-fearing]; [2] 2:240: provision for wives through bequest; [3] 4:11-12: the detailed inheritance rules [mawaris] that immediately follow the general bequest command; the relationship of wasiyyah and mawaris [inheritance] is debated — the Quran gives both; the Prophetic limit: the famous wasiyyah hadith: Sa'd ibn Abi Waqqas reported: 'I became seriously ill and the Prophet visited me; I said: O Messenger of God, I have property and only a daughter to inherit — may I bequeath two-thirds of my wealth? He said: No. I said: One-half? He said: No. I said: One-third? He said: One-third — and one-third is much [kathir]; it is better to leave your heirs wealthy than to leave them poor and begging from people' [Bukhari, Muslim]; the one-third limit is the maximum — anything beyond one-third requires all legal heirs' consent; the prohibition of bequest to legal heirs: the Prophetic hadith: 'la wasiyyata li-waritin' [No bequest is valid for a legal heir] [Abu Dawud, Tirmidhi]; the mawaris system already allocates shares to legal heirs; an additional bequest to an heir would disrupt this allocation; if all heirs consent, most schools permit bequest to an heir; conditions for a valid wasiyyah: [1] the testator [musi] must be: [a] adult and sane [mukallaf]; [b] making the bequest voluntarily [not under compulsion]; [c] the bequest may be made while terminally ill but with certain constraints; [2] the legatee [musa lahu] must be: [a] capable of ownership; [b] not a legal heir of the testator [per 'no bequest to an heir']; [c] specific enough to be identified; [3] the bequest amount: [a] must not exceed one-third of the net estate; [b] net estate = total estate minus debts and funeral expenses; [c] if the bequest exceeds one-third, the excess is void unless all legal heirs consent after the testator's death; [4] the subject matter [musa bihi]: must be capable of ownership and transfer; the revocability of wasiyyah: wasiyyah is revocable during the testator's life — unlike most contracts; the testator can modify or cancel the wasiyyah until death [or until falling into a legally defined terminal illness state where certain restrictions apply]; school differences: [1] all four major Sunni schools agree on the one-third limit and the prohibition of bequest to heirs; [2] minor differences in what constitutes 'capacity' for the terminally ill testator; [3] the Ja'fari Shi'i position: accepts bequest to legal heirs; [4] modern codifications: most Muslim-majority countries have codified wasiyyah law in civil codes based on the classical fiqh with some modifications) is Islam's most precisely bounded act of testamentary freedom.
One-Third and No More
The wasiyyah’s defining constraint is mathematical: one-third of the net estate, and not more. The Prophet’s dialogue with Sa’d ibn Abi Waqqas — refusing two-thirds, refusing one-half, accepting one-third with the comment that “one-third is much” — sets this limit with unusual precision for Islamic law. The Prophet’s reasoning is explicit: it is better to leave heirs with wealth than to leave them poor and dependent on others.
This limit exists in tension with 2:180’s broad command to “make a bequest for parents and near relatives” — which sounds like it requires bequests without specifying an upper bound. Classical fiqh resolved the tension by reading 2:180 as the general command (establishing the legitimacy of wasiyyah) and the Prophetic hadith as the limit on its scope. The result: a Muslim may bequeath up to one-third of their net estate to anyone who is not a legal heir, but not more.
No Bequest to Legal Heirs
The Prophetic hadith “no bequest is valid for a legal heir” (la wasiyyata li-waritin) is the other defining constraint. The Quranic inheritance system (mawaris) already allocates fixed shares to specified relatives. A wasiyyah that would give an heir an additional share disrupts this allocation — it effectively allows a testator to discriminate between heirs by supplementing some with additional bequests while others receive only their Quranic share. The prohibition prevents this circumvention.
If all heirs consent after the testator’s death, most schools permit bequest to an heir — but only with unanimous consent, ensuring that the benefited heir is not imposing on the others.
Net Estate, Not Gross
The one-third is calculated against the net estate: total assets minus outstanding debts and funeral expenses. This ordering — debts paid first, then wasiyyah, then inheritance — is consistent with the Quranic order (4:11-12 mentions debts before both bequests and inheritance). The deceased’s obligations take priority over their testamentary wishes.
