Use Allah’s beautiful names to call Him. E.g., Al-Rahman, Al-Raheem, Al-Khaliq
The Prophet (saw) said, “Every dua is kept back until you send blessings upon the Prophet.”
Face the qiblah
‘Umar (ra) narrated, “..then the Prophet (saw) turned to face the qiblah, then he stretched forth his hands and started to cry out to his Lord”
Raise your hands into the position of making dua
Have faith that your dua will be accepted and Allah will respond one way or another
Ibn al-Jawzi (rh) said. “I think part of the test is when a believer supplicates and receives no response, and he repeats the dua for a long time and sees no sign of a response. He should realise that this is a test and needs patience.”
Ask frequently – don’t lose hope. Remember, Allah’s kingdom is vast, so do not restrict yourself when asking Him for something.
Be firm in your asking - i.e. don’t say “Allah forgive me if you wish”, rather, beg Allah for exactly what you want.
