Chapter 2, Verse 203, The Cow
سُوۡرَةُ البَقَرَة
۞وَٱذۡكُرُواْ ٱللَّهَ فِيٓ أَيَّامٖ مَّعۡدُودَٰتٖۚ فَمَن تَعَجَّلَ فِي يَوۡمَيۡنِ فَلَآ إِثۡمَ عَلَيۡهِ وَمَن تَأَخَّرَ فَلَآ إِثۡمَ عَلَيۡهِۖ لِمَنِ ٱتَّقَىٰۗ وَٱتَّقُواْ ٱللَّهَ وَٱعۡلَمُوٓاْ أَنَّكُمۡ إِلَيۡهِ تُحۡشَرُونَ
And remember Allah during the appointed days. But whosoever hastens to leave in two days, there is no sin on him and whosoever stays on, there is no sin on him, if his aim is to do good and obey Allah (fear Him), and know that you will surely be gathered unto Him.
Chapter 20, Verse 103, Taha
سورة طه
يَتَخَٰفَتُونَ بَيۡنَهُمۡ إِن لَّبِثۡتُمۡ إِلَّا عَشۡرٗا
In whispers will they speak to each other (saying): "You stayed not longer than ten (days)."
Chapter 29, Verse 11, The Spider
سورة العنكبوت
وَلَيَعۡلَمَنَّ ٱللَّهُ ٱلَّذِينَ ءَامَنُواْ وَلَيَعۡلَمَنَّ ٱلۡمُنَٰفِقِينَ
Verily, Allah knows those who believe, and verily, He knows the hypocrites [i.e. Allah will test the people with good and hard days to discriminate the good from the wicked (although Allah knows all that before putting them to test)].
Chapter 89, Verse 2, The Dawn
سورة الفجر
وَلَيَالٍ عَشۡرٖ
By the ten nights (i.e. the first ten days of the month of Dhul-Hijjah).
Chapter 3, Verse 140, The family of Imran
سورة آل عمران
إِن يَمۡسَسۡكُمۡ قَرۡحٞ فَقَدۡ مَسَّ ٱلۡقَوۡمَ قَرۡحٞ مِّثۡلُهُۥۚ وَتِلۡكَ ٱلۡأَيَّامُ نُدَاوِلُهَا بَيۡنَ ٱلنَّاسِ وَلِيَعۡلَمَ ٱللَّهُ ٱلَّذِينَ ءَامَنُواْ وَيَتَّخِذَ مِنكُمۡ شُهَدَآءَۗ وَٱللَّهُ لَا يُحِبُّ ٱلظَّٰلِمِينَ
If a wound (and killing) has touched you, be sure a similar wound (and killing) has touched the others. And so are the days (good and not so good), We give to men by turns, that Allah may test those who believe, and that He may take martyrs from among you. And Allah likes not the Zalimun (polytheists and wrong-doers).
