(a) Invocation of Allah,
(b) Appeal to Allah,
Put faith in Allah. Seek His protection. Direct your prayers, requests, solicitations and supplications to Him and Him alone. Ask as much of His favours as you can. Know that Allah owns the treasures of the heavens and the earth. Not only He has given permission to ask for His mercy and favours, but also has promised to listen to your prayers. Invoke His help in difficulties and distress. Implore Him to grant you long life and sound health. Pray to Him for prosperity. Think over it that by simply granting you the privilege of praying for His favours and mercy, He has handed over the keys of His treasures to you. Whenever you are in need, pray, and He gives His favours and blessings.
Every true believer must seek help of Allah to avoid the company of unjust people who not only do not believe in Allah but have gone astray by not following the rules and regulations made by Allah to direct their behaviour in this world. Although good in the permanent life of Hereafter is the aim of all Muslims, but good in this world is also necessary because man has been asked by his creator Allah to take part in all activities of this world without breaking the rules and regulations, made by Him. So beseech Him for the good in both the worlds.
No matter how much wisdom you have, beseech Allah to guide you on the right path, whatever the field of enquiry or activity you are taking after. Seek help of Allah to keep you very close to the ways and means of the righteous and the pious servants of His, the surest road to success, in this and the next world, and to keep you away from the dishonest methods and hypocritical attitude of the astray shaitan, although they may appear profitable for a little while, but finally bring ruin and destruction in the end. Putting in the best efforts does not make your labour fruitful, because there are many unknown and uncontrollable forces working in the universe that can bring disappointment if Allah, who not only knows but has total control over all things and events, does not help you. So always invoke Allah.
We are responsible for what we do. If we make mistakes, by breaking laws of Shariat, we must admit our mistakes and humbly and sincerely seek forgiveness (with firm determination that we will not commit such sins any more) of our merciful Creator, who not only forgives faults but helps us to overcome our enemies and the enemies of Allah; and in this way, keeps away from us hardships and sorrows that they (enemies) might bring if Allah does not stop them, in answer to our supplications.
Sometimes you find requests are not immediately granted. Do not be disappointed. Fulfillment of desires rest in the true purpose or intention of the prayer. More often fulfillment is delayed because Allah wants to bestow upon you suitable rewards. In the meantime bear patiently hardships, believing sincerely in His help. You will get better favours, because, unknowingly you may ask for things which are really harmful to you. Many of your requests, if granted, may bring eternal damnation. So at times, withholding fulfillment is a blessing in disguise.
Do not turn to anyone but Allah to ask for fulfillment of all your wants and needs, and also makes it clear that there is no other way to get satisfaction of your desires except to invoke Allah, who answers whenever called by a supplicant. It brings you near Allah and keeps you on the right path. He answers to the cry for help because the love of Allah for His servants is much greater than the love of a mother for her children.
System of saying dua:
When saying dua raise your (man) arms up to the level of your chest. Do not open your arms apart in the right-left direction. They are held close to each other, forward. It in sunnat to begin the dua with hamd, with sana (praise of Allah) and durood (prescribed blessing invoked on the Prophet’s blessed soul) and to rub both palms gently on the face after dua. While making dua both hands should be opened towards the sky, apart from each other, and on the level with the chest. A woman does not stretch her hands forward while making dua but she keeps them inclined towards her face.
