sincere supplication (dua)

هُنَالِكَ دَعَا زَكَرِيَّا رَبَّهُۥ ۖ قَالَ رَبِّ هَبْ لِى مِن لَّدُنكَ ذُرِّيَّةً طَيِّبَةً ۖ إِنَّكَ سَمِيعُ ٱلدُّعَآءِ

At that, Zechariah called upon his Lord, saying, "My Lord, grant me from Yourself a good offspring. Indeed, You are the Hearer of supplication."

فَٱسْتَجَبْنَا لَهُۥ وَنَجَّيْنَـٰهُ مِنَ ٱلْغَمِّ ۚ وَكَذَٰلِكَ نُـۨجِى ٱلْمُؤْمِنِينَ

So We responded to him and saved him from the distress. And thus do We save the believers.

فَدَعَا رَبَّهُۥٓ أَنِّى مَغْلُوبٌ فَٱنتَصِرْ

So he invoked his Lord, "Indeed, I am overpowered, so help."
