Performing Tayammum and offering Salah individually
It is obligatory upon
men, whether at home or on a journey, to perform Salah in congregation. This is so whether they perform Tayammum or Wudu’ (ablution). It is not permissible for them to perform Salah individually due to Tayammum. What that man told you is not correct.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
