What is urinary incontinence, and is it permissible for someone afflicted with it to combine prayers, and what is the ruling on the order of combined prayers in a delayed combination, and how does a sick person pray the combined prayers in congregation in the mosque?

Urinary incontinence is the involuntary discharge of urine. The Hanbalis permit combining prayers for those afflicted with it, and they must observe the order between the combined prayers, acting on their opinion. As for the Shafi'is, they do not require ordering between combined prayers when performing Jum’ Takheer (delaying combining), but they do not permit combining for those with incontinence. The preponderant opinion is that unity of intention between the Imam and the Ma'mum (follower) is not a condition, so it is permissible to pray Dhuhr behind someone praying Asr, and Maghrib behind someone praying Isha.
