How can I get rid of gossip and grudge?
After I started listening to your lectures, I clung to prayer, the Qur'an and dhikr more. However, there is always something missing inside of me. I can't stand the injustice done by my husband's family and I gossip all the time. I can't help but feel a grudge against them. Actually, I just want to be busy with my worship, I want to raise my children as a worthy servant of my Lord. How can I get rid of this grudge?
Try not to exaggerate, being balanced in everything is what is required of us, including worship. You should keep yourself busy in the distress you have stated. Set yourself a rule of reading the Qur'an. For example, make it a rule to read ten pages of the Qur'an daily. Pray a lot. Have a daily dhikr. For example:
Salawat five hundred times, tawhid five hundred times, tasbih a thousand times...
Start by increasing them gradually.
Allah help you.
