Water falling from eyes
There are different forms of falling water from eyes. If the water falls because of crying or wood needle it doesn’t break the wuzu unanimously. However, if it occurs because of eye pain or because of the eye getting red the jurists have different opinions. Alauddin Hasfaki declared it wuzu breaker but Allama Ibne Aabideen narrated from Hafiz Ibni Humam that it doesn’t break the wuze. However, it’s better to make ablution again. Ibn e Humam proved this by the following saying of Imam Muhammad.
In the case of eye pain with flowing tears, the man should be ordered to make ablution for each prayer since it may be festering of the wound so he will be declared excused.
This statement indicates clearly that Imam Muhammad declared it just preferable and close to precaution, not necessary. Also, Molana Rasheed Ahmad Gangohi and Mufti Azizurrahman Usmani had the similar opinion.
