Making inquiries about the suitor before the engagement

Q 2: A man who recently became Multazim (practicing Muslim) proposed to me. Now he offers Salah (Prayer) and attends religious lectures regularly, to the extent that he travels to attend them in nearby villages. He comes from a descent family. When we inquired about him, we knew that he offers Salah regularly in the Masjid (mosque). Does this conform with the Hadith of the Prophet (peace be upon him) in which he said: "When you see a man frequenting the Masjid, testify that he is a Mu'min (believer)" ? The Messenger of Allah (peace be upon him) also said: "If someone with a satisfactory standard of Iman (Faith) and good conduct comes to you seeking marriage, give him (your daughter or sister) in marriage. If you refuse, that will lead to the spread of Fitnah (temptation) and great corruption in the earth." The Messenger of Allah (peace be upon him) has, indeed, spoken the truth.Please be advised that I have offered Salat-ul-Istikharah (Prayer for guidance), but I felt nothing, given that my father agrees to him as a suitor but my mother does not like his mother and his sister. Is it a mother's right to turn down a suitor for that reason, although his family is kind? What should I do? Should I turn him down because of my mother's refusal, or agree to marry him because he is a Multazim? May Allah benefit us and you.

(Part No. 18; Page No. 72) A: Your parents should inquire about any suitor and ask trustworthy people about him. If it becomes evident to you that he is religious and well-mannered, marry him and try to convince your mother. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
