This used to be one of my favourite prayers and I just realized it's quite difficult to find online. So I'm going to put it up here:
Allah, our Lord! Hidden and manifest, Creator Supreme and Fashioner Superb! Thine is the world we know and Thine the worlds we know not. Thy mercy envelops creation and Thy light dispels gloom. Burden us not with what we cannot bear and forgive us when we err.
Let us not squander Thy bounty and lose hope in Thy loving beneficence. Unto Thee we flee and cry in anguish. Hold us close when our feet fail and lead us with the righteous to victory. Why should we grieve and fear when Thou art near and why should we complain against Thy decrees when we know not what Thou hast prepared for us? Ignorant as we are, we know not the the joy that may lie hidden in sorrow and the sorrow that may lurk in joy.
We pray for those who have gone before us and beseech Thy forgiveness for our parents, in whose loving care we grew. Informed with wisdom let us grow in knowledge that comes of Thee. Suffer us not to envy the pleasures that others have and to languish in grief at the loss of what we have. Guard us against pride and lust and make us not vain and hypocritical. Let not passion make us wild and let not power blind us to the transient state of all that life offers.
Blessed is he who has surrendered his all unto Thee and who has won his peace in Thy pleasure. May our tears in constant remembrance of Thee sustain the heart and bring deliverance! Bless us with the fullness of life on earth and when the time comes make us return unto Thee united in the fellowship of Thy loving ones. Lord! Grant us above all, we pray, the vision of Thy countenance that Thou hast promised for those who are Thine.
