Musannaf Ibn Abi Shaybah

Hazrat Urwah says that due to boils, perform ablution only once.

Hazrat Saif states that Hazrat Mujahid had a boil which kept discharging, and because of it he would not perform ablution, and if it touched his clothes, he would not wash them.

Ibrahim was asked about a person who has many boils that keep discharging, so what should he do? He replied: He should keep washing their traces and perform ablution and pray.

Hazrat Sha'bi was asked about a person who has hemorrhoidal sores, so he replied that he should continue to perform prayer even if the flow reaches down to his feet.

Ibrahim was asked about a person who has blisters and their marks get on the clothes. He replied that there is no need to wash the clothes until it heals, and when it heals, then wash the clothes. Ibrahim used to pray in those clothes which had marks of pus from the blisters.

Hazrat Ummi says that she saw Hazrat Tawus praying in such clothes that, because of the marks of sores on his shins, they looked like leather.
