Allahumma yassir walatu'assir

i) Allahumma yassir wa la tu'assir (O Allah: Make things easier for me and don't make them difficult).

ii) Rabbishrah li sadri wa yassir li amri: (O my Lord: Open my heart for me and make my task easier for me).

iii) Rabbanaa Atina fiddunya hasanatan wa fil aakhirati hasanatan waqina azabannar (O my our Lord: give us the goodness of this world and the goodness of the hereafter and save us from the punishment of fire).

The key to getting our wishes answered is to pray to the Almighty with sincerity, understanding and from the heart.

I would also, and especially, strongly advise you against resorting to ‘formulas’, for there is a false notion that mimicking and parroting such ‘wazifas’ will get the results. That was not the way of the Prophet.
