It is obligatory
on the Waliy (a legally accountable person acting for a woman regarding marriage) to be careful when choosing a husband for the woman under his guardianship, asking about him and choosing a religious person of good conduct who deals kindly with people. Thus, you have to ask about whether the man establishes the fundamentals of Islam including Tawhid (monotheism), five obligatory daily Salahs, Zakah (obligatory charity), Sawm (fast) and Hajj as well as other good morals and characteristics. If he is so, you may marry him to her after seeking her permission, even if he commits some sins if you find no one better than him. (Part No. 18; Page No. 191) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
