Bleeding Gums and Wudu
Your ablution (wudu) would be nullified if redness preponderated in your saliva. The sign of which is if you were to spit, the redness of the blood would predominate over your saliva. [Shurunbulali, Maraqi al-Falah]
Ignore any misgivings. Either the redness predominates or it does not. There is no third option.
And Allah alone gives success.
By Shaykh Abu Yusha Yasin
