بسم الله الرحمن الرحيم
We begin with Allah’s blessed name, we praise him and we glorify him, seek his forgiveness and ask him to guide us. Whoever Allah guides, None can lead astray and whoever he misguides, None can guide. There is no power and no strength except from Allah, The most high, the Most great, the most powerful. We bear witness that there is no one worthy of worship but Allah Alone, and we bear witness that Prophet Muhammad (pbuh) is His slave-servant and the seal of His Messengers. We pray for peace and blessings on all the noble messengers and in particular on the last of them all “the blessed prophet Mohammad (pbuh)”
If one is well versed in Arabic and can make ‘dua’ in Arabic then it is not permissible to make ‘dua’ in any other language, but if one is unable to make ‘dua’ in Arabic then there is no harm in making ‘dua’ in a language one knows.
Although it is not considered forbidden to supplicate to ones lord in a language one knows, it is highly recommended to make ones supplications in prayer in the Arabic as it is the Sunnah of the blessed prophet (pbuh).
if I can then when inside in salah or I should make extra prostration/sperate prostration without salah to make dua?
You can make it either in the prostration of salah or in the saperate prostration.
can I make dua in prostration of fard sunnah and nafl salah too?
can I make my own dua in prostration besides quraan sunnah duas?
and last can I make dua in last rakat of salah after finishing durud?
if I can then can I make the dua in my own native language?
Yes, if you are unable to make supplications in Arabic.
cause I don't know arabic and can I make dua what I need in that part? or quraan sunnah duas?
Any Dua. And Allah alone knows the best.
I ask Allah to make this a sincere effort, seeking his pleasure, and I ask him to grant us refuge in him from the evils within ourselves, and that in our deeds. I ask him to grant us success in achieving whatever pleases him; And May Allah Shower His blessings and mercy upon our beloved Prophet Muhammad (pbuh), his family and his Companions and on all those who follow him until the final hour.Ask Your Question
