Ability to Perform Hajj, What Does it Imply?
     The ability to perform Hajj, which is one of its    essential conditions, includes the following:           A person must be healthy and physically fit. If     one is disabled by old age or a disease that is     incurable or is unable to perform Hajj for some     other similar reason, he may, if he is     financially capable, assign someone else to     perform Hajj on his behalf and at his expense.
     This will be discussed later under "Hajj On     Behalf of Another Person."
           The journey to Hajj must be safe so that the     pilgrim's life and possessions are safe and     secure from any danger. If one is afraid for     one's life from highwaymen or an epidemic or if     one is afraid to be robbed of one' s possessions,     then such a one is deemed as one of those who     cannot afford the journey for Hajj .
           There is, however, a difference of opinion among scholars    regarding the entry fees and other charges levied on    pilgrims. Can a person be excused and reckoned as unable    financially to perform Hajj because of these charges?    AshShafi'i and others are of the view that the presence    of these levies does qualify a person to be classified as    unable to perform Hajj, even though the levy involved may    be paltry. The Maliki scholars disagree for they do not    regard this as a sufficient reason for a person to be    deemed as unable to perform Hajj, unless the amount    involved is too exorbitant or is demanded repeatedly.
         As for those who live in the vicinity of Makkah, this    condition does not apply, for they are so close that they    can go for Hajj on foot.
         Some ahadith explain the Qur'anic words "those who can    afford the journey," (Qur'an 3.97) as meaning provision    of food and means of journey. Anas reports that the    Prophet (peace be upon him) when once asked about the    meaning of "those who can afford" said: "It means    possessing means of sustenance and transportation."
    (Ad-Daraqutni considers this hadith sound) Al-Hafiz    remarks: "Most probably its chain of transmitters is not    traceable to the Prophet (peace be upon him). Tirmidhi as    well has reported it on the authority of Ibn 'Umar but    its chain of transmitters is weak. Abdul Haqq remarked:    "All its chains of transmitters are weak." Ibn Al-Mundhir    says: "It is not traceable to the Prophet (peace be upon    him) and the correct position is that it is a sound but    incompletely transmitted hadith whose chain of    authorities does not go back to the Prophet (peace be    upon him)."
         Ali (may Allah be pleased with him) narrates that the    Prophet (peace be upon him) once said: "He who possesses    sufficient provisions and means of journey for the    performance of Hajj and yet does not do so, let him die    the death of a Jew or a Christian." For Allah says in the    Qur' an: "Pilgrimage thereto is a duty men owe to Allah -    those who can afford the journey." (Transmitted by    Tirmidhi, but among the narrators of this hadith are    included "Halal" ibn Abdullah, who is unknown, and    "Al-Harith" whom Ash-Sha'abi and others have described as    a liar)         All these ahadith are weak in authority, yet most    scholars regard provisions and means of journey as a    necessary condition for Hajj. If a person has neither the    necessary provisions nor means of travel, he is not    obligated to perform Hajj.
         Ibn Taimiyyah says: "These ahadith are musnad (A report    which is traceable in uninterrupted ascending order of    the narrators to its first authority) and have a sound    chain of authorities, some are mursal (A hadith    transmitted by a successor (atabi+), young or old,    without mentioning the Companion who might have heard it    from the Prophet directly. Ash-Shafi'i considers such a    hadith weak, while Abu Hanifah and Malik consider it    sound) and others are mauquf. (A hadith reported from a    Companion through words or acts uninterruptedly or    otherwise) They all prove that the ability to arrange    one's provisions and possession of means of journey is a    necessary prerequisite for Hajj, and this despite the    fact that the Prophet (peace be upon him) knew that many    of the people (in his time) were able to go for Hajj on    foot.
         Similarly the words of Allah: "Pilgrimage thereto is a    duty men owe to Allah - those who can afford the journey"    underline the fact that ability and power are the    necessary prerequisite for all forms of worship. It    signifies the unspecified power or a little bit more than    what may be necessary. In the case of sawm (fasting) and    salah (obligatory prayers) the financial ability is    superfluous and is not specified in the Qur'an, unlike    Hajj for which it is an important requirement. Similarly,    Hajj is a form of worship which involves traveling for    which one must be in possession of sufficient means to    support oneself (and one' s family), as well as be able    to shoulder the cost of the journey as in jihad.
         In this regard we may refer to the Qur'anic verse    (9.91-92) "Nor is there any blame on those who find no    resources to spend, nor is there (blame) on those who    come to you to be provided with mounts, and when you    said, 'I can find no mounts for you,."'         In Al-Muhadhib we read: "If someone has the money to buy    provisions and the passage to Hajj but he needs it to pay    his debts, Hajj is not binding on him, whether the    settlement of the debt is required immediately or is due    after a time. The debts that are due for immediate    settlement must be paid at once, whereas the Hajj may be    performed later on in life. But if he spends all that he    has on Hajj he may not be in a position to pay off his    debt."
         Similarly, if one is in need of a dwelling or a servant    to help him, he may be classified as unable to perform    Hajj. Likewise, if one needs to take a wife because he    fears he may not be able to avoid evil, he must get    married, for it is his immediate need. Furthermore, if    one needs goods for his business to obtain requisite    resources therefrom, such a one, according to Abul    'Abbas, Ibn Sarih, may be classified as unable to perform    Hajj in view of his specific need. Al-Mughni says: "If    the debt is owed to a wealthy person who does not demand    immediate settlement of the loan, defers settlement to a    later stage, and is ready to permit the debtor to proceed    for Hajj, then such a debtor is (technically) able to    perform Hajj. But in case the lender cannot afford to    defer settlement of the loan, the debtor would be    reckoned as unable to perform Hajj."
         According to the Shafi'i school: "If someone offers    another a free passage for Hajj, one is not obliged to    accept the offer, for it is a favor and involves distress    of being obliged to another person. If, however, such an    offer is made by one' s son to perform Hajj, then one is    obligated to do so, for one can perform it without being    beholden to anyone else."
         The Hanbali school is of the view that an offer of    financial help by someone else does not obligate a person    to perform Hajj, nor does this classify him as    (financially) capable of performing it, whether the offer    comes from a stranger or a relative and whether the offer    provides means of travel and provision, or linanacial    help as such.
