Is it permissible to combine Wudu (ablution) and Tayammum (dry ablution) when one is unable to wash some body parts due to fear of the cold?

Fear of cold water does not permit abandoning ablution (Wudu'). Instead, one must take measures to prevent harm, such as heating the water or performing ablution in an enclosed space. If no means are available and it is possible to wash some limbs without harm, then what is possible should be washed, and tayammum (definition) (dry ablution) should be performed for the rest. It is permissible to combine Wudu' and tayammum, but it is more cautious to perform tayammum after Wudu' to avoid disagreement.
