Should a person suffering from flatulence perform ablution again for supererogatory prayers after a temporary emission that occurred after the obligatory prayer, and what should their intention be when performing ablution in this case?

Scholars differed regarding the ablution of a person afflicted with incontinence. Is it obligatory for him to perform ablution for each obligatory prayer after its time has begun (the view of Abu Hanifa, Al-Shafi'i, and Ahmad, which is the more cautious opinion and adopted by the majority)? Or is it permissible for him to perform one ablution for all prayers as long as it is not invalidated by another nullifier (the view of Malik)? If the afflicted person experiences an impurity other than the continuous one, he must repeat his ablution, for the Prophet, peace and blessings be upon him, said: "Allah does not accept the prayer of anyone of you if he passes wind until he performs ablution." Scholars have unanimously agreed that purity is a condition for the validity of prayer. The intention is made in the heart, for the purpose of purification for prayer.
