19:26
فَ كُلِ ى وَ ٱشْرَبِ ى وَ قَرِّ ى عَيْنًا فَ إِمَّا تَرَيِ نَّ مِنَ ٱلْ بَشَرِ أَحَدًا فَ قُولِ ىٓ إِنِّ ى نَذَرْ تُ لِ ل رَّحْمَٰنِ صَوْمًا فَ لَنْ أُكَلِّمَ ٱلْ يَوْمَ إِنسِيًّا
So eat and drink and be contented. And if you see from among humanity anyone, say, 'Indeed, I have vowed to the Most Merciful abstention, so I will not speak today to [any] man.' "
21:45
قُلْ إِنَّ مَآ أُنذِرُ كُم بِ ٱلْ وَحْىِ وَ لَا يَسْمَعُ ٱل صُّمُّ ٱل دُّعَآءَ إِذَا مَا يُنذَرُ ونَ
Say, "I only warn you by revelation." But the deaf do not hear the call when they are warned.
2:270
وَ مَآ أَنفَقْ تُم مِّن نَّفَقَةٍ أَوْ نَذَرْ تُم مِّن نَّذْرٍ فَ إِنَّ ٱللَّهَ يَعْلَمُ هُۥ وَ مَا لِ ل ظَّٰلِمِينَ مِنْ أَنصَارٍ
And whatever you spend of expenditures or make of vows - indeed, Allah knows of it. And for the wrongdoers there are no helpers.
3:35
إِذْ قَالَتِ ٱمْرَأَتُ عِمْرَٰنَ رَبِّ إِنِّ ى نَذَرْ تُ لَ كَ مَا فِى بَطْنِ ى مُحَرَّرًا فَ تَقَبَّلْ مِنِّ ىٓ إِنَّ كَ أَنتَ ٱل سَّمِيعُ ٱلْ عَلِيمُ
[Mention, O Muhammad], when the wife of 'Imran said, "My Lord, indeed I have pledged to You what is in my womb, consecrated [for Your service], so accept this from me. Indeed, You are the Hearing, the Knowing."
