How should one who is afflicted with the passing of gas during prayer perform the prayer?

Question:
A questioner says: I am a young man afflicted with a disease, may Allah protect you from it, which is the constant passing of gas during prayer. Because of this disease, I have been prevented from performing the regular voluntary prayers (rawatib), and I am also plagued by doubt regarding my ritual purity in the obligatory prayers I do perform. I ask you to inform me what I should do in this matter. May Allah reward you with good!

Answer:
There is no harm, my brother. Pray the voluntary and obligatory prayers all together; pray these and those, the obligatory prayers, the regular voluntary prayers, and others. You are excused. The one who has gas, or constant urinary incontinence, or a woman with continuous irregular bleeding, each prays according to his or her condition. However, one does not perform ablution except when the time for prayer enters. When the time for the midday prayer (Zuhr) enters, one performs ablution and prays Zuhr and its regular voluntary prayers, and any other voluntary prayers one wishes, and reads the Qur'an, and continues until the time for the afternoon prayer ('Asr) enters. When the time for 'Asr comes and something exits, one performs a second ablution for 'Asr, and continues to pray 'Asr and whatever voluntary prayers are possible before it, and continues to remember Allah until the sun sets while remaining in a state of purity. When the sun sets, one performs ablution for the sunset prayer (Maghrib) and prays Maghrib and its voluntary prayers, and likewise for the night prayer ('Isha'), whether it is gas, urine, or anything else that exits from a person, it does not harm him. Praise be to Allah, [Surat al-Taghabun: 16].
And the Prophet (peace and blessings be upon him) said to the woman with continuous bleeding, when the blood was constant with her: So when the time enters, perform ablution and pray the voluntary and obligatory prayers all together, and praise be to Allah.
