Is it permissible for the questioner's father to perform tayammum for prayer, given that he sustained severe burns that prevent him from using water, and what is the interpretation of the recurring dream he has of a wild white camel?

If a Muslim is unable to use water due to illness, he should perform tayammum (definition) (dry ablution) and never abandon prayer, unless he loses consciousness. The obligation was to inquire about the ruling, not to abandon prayer, because abandoning it is one of the greatest sins. The Prophet, peace and blessings be upon him, said: "The covenant between us and them is prayer; whoever abandons it has disbelieved." He must make up the missed prayers and seek forgiveness for abandoning prayer, and what he saw in the dream may be a warning of the dire consequences of neglecting prayer.
