Hazrat Shaikh Moulana Muhammad Zakariyya (rahmatullahi ‘alaih) once mentioned the following advice for girls who are getting married:
In order to gain success in Deen and dunya (i.e. in this world and the next), and in order to enjoy a pleasant relationship with one’s in-laws, a girl should ensure that after nikaah, she should conduct with humility when interacting with her in-laws. She should also make a point of showing them mahabbat and affection when interacting with them, and she should serve them (to the best of her ability, within the limits of sharee‘ah). This quality is among the salient qualities found among the women of our household.
It is noticed that those girls who, after nikaah, adopt a humble approach with their in-laws, they win the hearts of their in-laws. On the contrary, those girls who show a little pride and attitude when dealing with their in-laws, their in-laws lose respect and regard for them in their hearts. Hence, a girl should always keep this advice in mind.
