إِذْ جَعَلَ ٱلَّذِينَ كَفَرُوا۟ فِى قُلُوبِهِمُ ٱلْحَمِيَّةَ حَمِيَّةَ ٱلْجَٰهِلِيَّةِ فَأَنزَلَ ٱللَّهُ سَكِينَتَهُۥ عَلَىٰ رَسُولِهِۦ وَعَلَى ٱلْمُؤْمِنِينَ وَأَلْزَمَهُمْ كَلِمَةَ ٱلتَّقْوَىٰ وَكَانُوٓا۟ أَحَقَّ بِهَا وَأَهْلَهَا ۚ وَكَانَ ٱللَّهُ بِكُلِّ شَىْءٍ عَلِيمًۭا
When those who disbelieve had set up in their hearts zealotry, the zealotry of the Age of Ignorance, then Allah sent down His peace of reassurance upon His messenger and upon the believers and imposed on them the word of self-restraint, for they were worthy of it and meet for it. And Allah is Aware of all things.
Surah Al-Fath(48:26)
Sahih al-Bukhari
Witr Prayer
Chapter: What is said regarding the Witr prayer
Narrated `Abdullah bin `Umar:
The Prophet (ﷺ) said, "Night prayer is offered as two rak`at followed by two rak`at and so on, and if you want to finish it, pray only one rak`a which will be witr for all the previous rak`at." Al-Qasim said, "Since we attained the age of puberty we have seen some people offering a three-rak`at prayer as witr and all that is permissible. I hope there will be no harm in it."
