Ruling on a sick person leaving off prayer during his period of illness

From Riyadh, the listener Hasan ibn Hadi sent a question and said: Some sick people do not perform the obligatory prayer during their illness, either because they are unable to do so, or because they give themselves hope that they will make it up after recovering. Is the prayer of a sick person who cannot get out of his bed without performing wudu' valid, and wherever he is, he turns his face, and he is on his bed? We ask for your guidance. May Allah reward you with good.
Answer: Prayer is obligatory upon the sick person. The obligatory prayers of Zuhr, 'Asr, Maghrib, 'Isha', and Fajr are obligatory upon the sick person according to his ability, and it is not permissible for him to leave them off. Rather, he must pray them according to his condition, based on the saying of the Prophet (peace and blessings be upon him) to the sick man who asked him: narrated by al-Bukhari in his Sahih, from the hadith of 'Imran ibn Husayn (may Allah be pleased with him), and al-Nasa'i narrated it and added: .
This is what is obligatory upon the sick person: he should pray standing if he is able. If he is unable, he prays sitting, bowing and prostrating. If he is unable to sit, he prays on his side, reciting and performing the verbal remembrances, and performing the physical actions by intention: bowing by intention, prostrating by intention, rising from bowing by intention, and rising from prostrating by intention, along with the prescribed remembrances. If he is unable, he prays lying on his back with his feet toward the qiblah. He says takbir and recites, then says takbir and bows by intention. Then he says, "Allah hears the one who praises Him," by intention, rising from bowing. Then he says takbir intending prostration and says, "Glory to my Lord, the Most High, Glory to my Lord, the Most High." Then he says takbir intending to rise from prostration, sitting between the two prostrations by intention, and says, "My Lord, forgive me, My Lord, forgive me." Then he says takbir intending the second prostration, and so on. This is because Allah says: [al-Taghabun: 16], and this is his ability. He does not have the right to leave off prayer. If he is unable to use water, he performs tayammum with dust, with the earthy ground, wiping his face and his hands. If he cannot use water, or if there is no one to perform wudu' for him. Yes.
