Question: A person performed dry major ablution (tayammum) instead of taking major ablution (ghusl), because he had an excuse to avoid him from using water; and then he obtained back the opportunity to use water. Does he have to take major ablution with water again? Because we know that, when we perform a dry ablution instead of simple ablution (wudu) and we find water, dry ablution is broken. Using the same logic, is dry major ablution broken if someone finds and can use water afterwards? There are people saying: “No, it doesn’t!”, but they can’t bring forth any evidence or a logical explanation to their comment.
Although, in most of the Islamic jurisprudence reference books it is said that simple dry ablution (tayammum) is broken when water is found afterwards; actually neither simple dry ablution nor major dry ablution is broken when water is found afterwards!
The reason is: the presence of water does not make the ablution or the major ablution a necessity. Instead, it is just an obstacle to perform another dry ablution from that time on; that’s all. What break a performed ablution are things you ought to do at the toilet. These are only winding, urinating and defecating. What would require someone to take a new major ablution (ghusl) are: having sexual intercourse, ejaculating awake or in sleep, and women’s ends of menstruation or postpartum periods. Finding water does not fall under any of these categories, so it does not break any kinds of dry ablution.
