Allah (SWT) listen to all the prayers and grants His mercy to every sincere person who seeks from Allah. We might see the response of our prayers soon, and it can be delayed as Allah knows the best time and situation to grant us our wishes. The response of our prayers can be saved for us for the future according to what is good for us. We should keep on sincerely seeking from Allah with faithful hearts that Allah listens and responds according to our interest.
Wassalam.
