Chosen Islamic Manners

*One should do good deeds when he asks Allah.
*It is appropriate that a Muslim perform Wudhu before asking Allah. It has been narrated in the hadeeth of Abu Musa al-Asha'ri () that when the Prophet () left Hunain, he () asked for water, and made the wudhu. He then raised his hands and said: 'O Allah forgive Ubaid b. Aamir!' I saw the whiteness of his armpits.
*The intention of the one asking Allah should be good. It has been narrated that Musa () said:

[Mûsa (Moses)] said: "O my Rubb! Open for me my chest (grant me self-confidence, contentment, and boldness). And ease my task for me; and make loose the knot (the defect) from my tongue, (i.e. remove the incorrectness from my speech) [That occurred as a result of a brand of fire which Mûsa (Moses) put in his mouth when he was an infant]. That they understand my speech, and appoint for me a helper from my family, Hârûn (Aaron), my brother; increase my strength with him, and let him share my task (of conveying Allah’s Message and Prophethood) that we may glorify You much, and remember You much. Verily! You are of us Ever a Well-Seer. (20:25-35)

*The one asking Allah should raise his complaints to Allah and show his dire need to Him. Allah says:

He said: "I only complain of my grief and sorrow to Allah, and I know from Allah that which you know not.” (12:86)

And in the Du'aa of Musa ():

So he watered (their flocks) for them, then he turned back to shade, and said: "My Rubb! Truly, I am in need of whatever good that You bestow on me! (28:24)

*One should ask Allah saying the best of Du'aa and while using the best of words.
