How does a woman afflicted with hemiplegia who finds it difficult to perform ablution (wudu') perform ablution or dry ablution (tayammum)? And should sand be brought to her, or should she perform tayammum by striking a dust-free wall? And what are the characteristics of her tayammum and prayer?

The sick person who is unable to bring water for ablution or to move should assess their situation: If they find someone to bring them water and help them perform ablution, then ablution becomes obligatory for them. If they do not find anyone to assist them, then tayammum (dry ablution) is prescribed for them, and their ruling is like that of someone who has lost access to water.

If they are able to wash some of the parts of ablution, they should wash what they can and perform tayammum for the rest.

The manner of tayammum: One strikes the earth with their hands once and wipes their face and palms.

If a sick person prays with tayammum and then water becomes available to them after the prayer, they are not obliged to repeat it, because they have fulfilled what was required of them.

Tayammum on a wall is permissible if it is not painted. If it is painted, it is permissible if there is dust on it.

The prayer of a sick person unable to move: They pray according to their ability. If they are unable to stand, they pray sitting. If they are unable to sit, they pray by gesturing (i'maa). If they are unable to sit, they pray lying down and gesture, with prostration being lower than bowing. Prayer does not cease to be obligatory for a Muslim as long as their intellect is sound; rather, they pray according to their condition.
