Touching a woman

Q: My father owns a store, and he often touches women's hands unintentionally while dealing with them in trade. Is he obliged to perform Wudu' (ablution) for touching women's hands? Please advise, may Allah reward you.

A: It is obligatory for the man concerned to avoid touching any Ajnabiyyah (a woman other than a wife or permanently unmarriageable female relatives), but if this happens unintentionally, as in the case of your father, he is pardoned and his Wudu' is not invalidated. (Part No. 4; Page No. 118) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
