How can a person who is partially paralyzed do wudoo’ and pray?
Question

                There is a woman who is affected by partial paralysis and it is difficult for her to do wudoo’.

 My question: How can she do wudoo’ or tayammum?

Should earth be brought to her, or what?

Can she do tayammum striking her hands on the wall (even though there is no dust on it) or what should she do?

How should her tayammum be done?

How should her prayer be done?.
Praise be to Allah.Firstly: 
If a person 
    is sick and cannot bring water and do wudoo’ with it, or he is incapable of 
    moving, his situation should be examined further: 
If there is 
    someone who can bring water at the time of prayer and help him to do wudoo’, 
    then wudoo’ is obligatory in his case. 
If there is 
    no one who can help him do wudoo’, then it is prescribed for him to do 
    tayammum in that case, and he comes under the same ruling as one who does 
    not have any water and cannot find any. 
That is 
    because Allaah, may He be exalted, says (interpretation of the meaning):
“So 
    keep your duty to Allaah and fear Him as much as you can”

    [al-Taghaabun 64:16]
And the 
    Prophet  (peace and blessings of Allaah be upon him) said: “If I command 
    you do a thing, do as much of it as you can.” Narrated by al-Bukhaari 
    (7277); Muslim (1337). 
Ibn Qudaamah 
    (may Allaah have mercy on him) said in al-Mughni (1/151): 
If a person 
    is sick and unable to move, and there is no one who can bring him water, 
    then he is like one who has no water, because he has no way to obtain any 
    water. So he is like one who finds a well but has no means of drawing water 
    from it. 
If he has 
    someone who can bring him water before the time for prayer ends, then he is 
    like one who can find water, because he is in the same position as one who 
    finds something with which to draw water within that time. 
If he is 
    afraid that the time will end before he comes, then Ibn Abi Moosa said: he 
    may do tayammum, and he does not have to repeat wudoo’. This is the view of 
    al-Hasan, because he is without water during the time for prayer, so he is 
    exactly like one who has no water. End quote. 
Al-Mardaawi 
    said in al-Insaaf (1/265): 
If the sick 
    person is unable to move and there is no one to do wudoo’ for him, then he 
    comes under the same ruling as one who has no water. 
If he fears 
    that the time for prayer will end if he waits for someone to do wudoo’ for 
    him, he should do tayammum and pray, and he does not have to repeat it 
    according to the correct view. End quote. 
Shaykh 
    al-Islam Ibn Taymiyah (may Allaah have mercy on him) said in Sharh 
    al-‘Umdah (1/433-434): 
If he is not 
    able to use water because he is unable to move to where the water is, and he 
    does not have anyone to bring water to him, then he is like one who has no 
    water. If he has someone who can bring water to him within the time (for the 
    prayer), then he is like one who has water. End quote. 
It says in
    al-Mawsoo’ah al-Fiqhiyyah (14/260): 
The one who 
    is incapacitated and cannot use water should do tayammum, and he does not 
    have to repeat it, like one who is forced, detained or tied up near water, 
    or one who is afraid of animals, whether he is travelling or not, because he 
    comes under the same ruling as one who has no water. The Messenger of Allaah 
     (peace and blessings of Allaah be upon him) said: “Clean earth is a 
    means of purification for the Muslim, even if he cannot find water for ten 
    years. When he finds water, he should let it touch his skin, for that is 
    good.” End quote.

Secondly: 
If he is 
    able to wash some of the parts of the body that are washed in wudoo’, but 
    his sickness prevents him from washing the rest, then he has to wash 
    whatever he can of the parts that are washed in wudoo’, and he should do 
    tayammum instead of the parts that he cannot wash. This has been explained 
    in the answer to question no. 67614. 
Thirdly: 
With regard 
    to how tayammum is done: 
Shaykh Ibn 
    ‘Uthaymeen said in al-Sharh al-Mumti’ (1/488): 
In my view, 
    how it is to be done in accordance with the Sunnah is as follows: he should 
    strike the earth with his hands once, without spreading the fingers, and 
    wipe his face with his hands, then he should wipe one hand with the other. 
    Thus tayammum will be completed. End quote. 
It has been 
    described in detail in question no. 
    21074. 
Fourthly: 
If a sick 
    person who is unable to use water does tayammum, then it becomes easier for 
    him to use water after he has finished his prayer, he does not have to 
    repeat it, because he has done what is required of him and what he is 
    commanded to do. 
Shaykh 
    al-Islam Ibn Taymiyah said in Sharh al-‘Umdah (1/425): 
Because 
    Allaah enjoined one prayer at a specific time which is to be done according 
    to what one is able to do, and the condition is waived in the event that one 
    is unable to fulfil it. The words of the Prophet  (peace and blessings 
    of Allaah be upon him), “Clean earth is a means of purification for the 
    Muslim” and “Soil is sufficient for you” indicate that it takes the place of 
    water in all cases. End quote. 
Fifthly:  
The scholars 
    differed with regard to doing tayammum by striking the walls of one’s house, 
    based on their differences of opinion as to the meaning of the verse in 
    which Allaah says (Interpretation of the meaning): 
“perform 
    Tayammum with clean earth”
[al-Nisa’ 
    4:43]
The correct 
    view is that what is meant by sa’eed (clean earth) is the face of the 
    earth, whether it is dirt, sand or stones, etc. 
Based on 
    this, if the wall is not covered with anything, then it is permissible to 
    use it for tayammum, whether there is dust on it or not, because it is made 
    of clean earth. But if it is covered with wood or paint, then this wood or 
    paint is not sa’eed (clean earth) and it is not valid to use it for 
    tayammum, unless there is dust on it, because dust comes under the heading 
    of sa’eed.

    question no. 36774. 
Sixthly: 
With regard 
    to the way in which a sick person who is unable to move should pray: 
It says in
    al-Mawsoo’ah al-Fiqhiyyah (26/208): 
The sick 
    person or the one who is suffering partial paralysis should do those pillars 
    (essential parts) of the prayer that he is able to, according to the 
    majority of fuqaha’, because the one who is unable to do something is not 
    obliged to do it. If he is unable to stand, he may pray sitting and he 
    should bow and prostrate. If he is unable to do that, then he should pray 
    sitting and lean forward for bowing and prostration, leaning more for 
    prostration than bowing. If he is unable to sit, then he should lie down and 
    use gestures, because the essential parts are waived if one is unable to do 
    them, and he should do as much as he is able. 
‘Imraan ibn 
    Husayn (may Allaah be pleased with him) said: I fell sick and the Messenger 
    of Allaah  (peace and blessings of Allaah be upon him) visited me and 
    said: “Pray standing, and if you cannot, then sitting, and if you cannot, 
    then lying on your side, making gestures.” End quote. 
Shaykh 
    Saalih al-Fawzaan was asked: I have a father who is sick and paralyzed on 
    the left side of his body, which he is completely unable to move. Hence he 
    cannot walk or move or do anything for himself or relieve himself. This has 
    been the case for ten years. But three or four months ago this sickness got 
    even worse. Is it permissible for him to stop praying for this reason, 
    because he cannot purify himself for prayer? 
If it is not 
    permissible, how should he purify himself and pray? 
What should 
    he do about the prayers that he missed in the past because of his sickness, 
    because he thought that so long as he was like that, he was excused from 
    praying? 
He replied: 
The Muslim 
    is not excused from praying so long as he is of sound mind, but he should 
    pray according to his situation, because Allaah says (interpretation of the 
    meaning): 
“So keep 
    your duty to Allaah and fear Him as much as you can”

     [al-Taghaabun 64:16] 
And the 
    Prophet  (peace and blessings of Allaah be upon him) said: “Pray 
    standing, and if you cannot, then sitting, and if you cannot, then lying on 
    your side.” 
If your 
    father who is stricken with paralysis can do wudoo’ by himself using his 
    sound hand, or if someone else can help him to do wudoo’, then he must do 
    that. 
If he is not 
    able to do wudoo’ using water, then he must do tayammum using earth. 
If he cannot 
    do tayammum by himself, then someone else should do tayammum for him: one of 
    his family who is taking care of him or one of those who are present should 
    strike his hands on the ground, and wipe his face and hands, intending that 
    to be a purification for him, then he should pray according to his 
    situation, sitting or lying on his side, gesturing with his head for bowing 
    and prostrating, according to what he is able to do. 
If he cannot 
    gesture with his head because of the paralysis, then he may indicate bowing 
    and prostrating with his eyes.
 Religion is 
    easy, praise be to Allaah, but that does not mean that he should give up 
    praying altogether. Rather he should pray according to his situation as we 
    have described. And he has to make up the prayers that he missed, as best he 
    can. End quote.
