1 – The one who is making du’aa’ should believe in Tawheed with regard to the divinity, Lordship, names and attributes of Allaah. In order for Allaah to respond to the du’aa’, it is essential that the person should be responding to his Lord by obeying Him and not disobeying Him.
2 – Sincerity towards Allaah alone in making du’aa’. Du’aa’ is worship, as the Prophet (peace and blessings of Allaah be upon him) said, so sincerity (ikhlaas) is a condition of its being accepted.
3 – We should ask of Allaah by His most beautiful names.
4 – We should praise Allaah as He deserves before we call upon Him.
5 – Sending blessings upon the Prophet (peace and blessings of Allaah be upon him). The Prophet (peace and blessings of Allaah be upon him) said: “Every du’aa’ is kept back until you send blessings upon the Prophet (peace and blessings of Allaah be upon him).”
6 – Facing towards the qiblah. (it is mustahabb to face towards the qiblah when making du’aa’, and to raise the hands)
7 – Raising the hands.
8 – Having certain faith that Allaah will respond, and focusing with proper presence of mind.
9 – Asking frequently. A person should ask his Lord for whatever he wants of the good things in this world and the Hereafter, and he should beseech Allaah in du’aa’, and not seek a hasty response.
10. He should be firm in his du’aa’.
11 – Beseeching, humility, hope and fear.
12 – Saying du’aa’s three times.
13 – Ensuring that one’s food and clothing are good (i.e., halaal). Ibn Rajab (may Allaah have mercy on him) said: Ensuring that one’s food, drink and clothing are halaal, and that one is nourished with halaal, is a means of having one’s du’aa’ answered.
14 – Saying du’aa’ silently and not out loud.
