I heard the Messenger of Allah (ﷺ) say, “That which is lawful is clear and that which is unlawful is clear, and between the two of them are doubtful matters about which many people do not know. Thus he who avoids doubtful matters clears himself in regard to his religion and his honor, but he who falls into doubtful matters [eventually] falls into that which is unlawful, like the shepherd who pastures around a sanctuary, all but grazing therein.
On the authority of Abdullah, the son of Umar ibn al-Khattab (ra), who said: I heard the Messenger of Allah (ï·º) say, “Islam has been built on five [pillars]: testifying that there is no deity worthy of worship except Allah and that Muhammad is the Messenger of Allah, establishing the salah (prayer), paying the zakat (obligatory charity), making the hajj (pilgrimage) to the House, and fasting in Ramadhan.”
Allah (S.W.T) is the ultimate helper. He is the Al-Rahman and Al-Rahim, he knows the problems of his servants. He wants them to pray and remember him at times of hardship so that he is relieved of his problems. Prophet Muhammad S.A.W has taught during his life certain duas for problems. In order for any wazifa or dua to work in your favor and solve your problems, one must follow certain guidelines.
