Effectiveness Of Supplication (Dua)
Allah had said in Quran, (translation): you may like something but it’s bad for you and you may dislike something but it’s good for you. Allah knows and you don’t. Secondly Allah is not bound to your dua. He gives you according to his wisdom. Thirdly, it’s Allah’s right that one should ask him and it’s duty of us to ask him. If he gives everything what we ask then we might fall into trouble as those things may not be good for us.
