Sincere supplication (du'ā)

وَأَعْتَزِلُكُمْ وَمَا تَدْعُونَ مِن دُونِ ٱللَّهِ وَأَدْعُوا۟ رَبِّى عَسَىٰٓ أَلَّآ أَكُونَ بِدُعَآءِ رَبِّى شَقِيًّا

And I will leave you and those you invoke other than Allāh and will invoke my Lord. I expect that I will not be in invocation to my Lord unhappy [i.e., disappointed]."

وَزَكَرِيَّآ إِذْ نَادَىٰ رَبَّهُۥ رَبِّ لَا تَذَرْنِى فَرْدًا وَأَنتَ خَيْرُ ٱلْوَٰرِثِينَ

And [mention] Zechariah, when he called to his Lord, "My Lord, do not leave me alone [with no heir], while You are the best of inheritors."
