Allah has named Himself Al-Mujeeb, which means the One who responds. Justas we are certain that the Qur'an is true, we must be certain that Allah, Al-Mujeeb, will answer our call. We should never think that Allah will not answer, because by feeling so, we are denying this attribute (siffat) of Allah. Allah may delay answering your prayer for a number of reasons; one is to test your trust in Him. We all say we believe Allah is the Al-Mujeeb when everythinglands at our feet, but what about when we don't immediately see the fruits of our du'a? I knew a woman who was telling the story of how her husband did not pray. When she married him, shedidn't know, and as the marriage progressed she discovered that he was skeptical of religion as well.So she would wake up every night for qiyam al-layl (the night prayer) and plead with Allah to guide Him. Do you know how long she prayed for? Two years. And she says it was so unexpected; he came home from a business trip with a complete change of heart. It turns out that on the plane he was seated next to a great sheikh who began talking to him. And that is how he changed. Allah does not place a burden on us greater than we can bear. If the answer to your du`a' has been delayed, it's because Allah KNOWS you can handle it. He tests those whom He loves, so keep asking and remember that Allah makes with hardship ease. And remember, as with tawakkul, we need to exerteffort as well
