Islamic Duas and Supplications

Nay,- whoever submits
His whole self to Allah
And is a doer of good,-
He will get his reward
With his Lord;
On such shall be no fear,
Nor shall they grieve (Surah Al Baqarah 2:112)

بِسْمِ اللَّهِّ اللَّهُمَّ جَنِّبْنَا الشَّيْطَانَ وَجَنِّبِ الشَّيْطَانَ مَا رَزَقْتَنَا

"I am having relations in the name of Allah. O Allah save us from Satan and keep him away from the children You grant us". The child that is born after the recitation of this dua will never be harmed by Satan.(Bukhari, Muslim)

Note: This dua must be read for if Allah's name is not taken, the Satan's sperm enters with the man's (As in marginal notes of Hisnul Hasin)

And besides Him ye have
Neither patron nor helper
Surah Al Baqarah (2:107)
