Chapter 2, Verse 184, The Cow
سُوۡرَةُ البَقَرَة
أَيَّامٗا مَّعۡدُودَٰتٖۚ فَمَن كَانَ مِنكُم مَّرِيضًا أَوۡ عَلَىٰ سَفَرٖ فَعِدَّةٞ مِّنۡ أَيَّامٍ أُخَرَۚ وَعَلَى ٱلَّذِينَ يُطِيقُونَهُۥ فِدۡيَةٞ طَعَامُ مِسۡكِينٖۖ فَمَن تَطَوَّعَ خَيۡرٗا فَهُوَ خَيۡرٞ لَّهُۥۚ وَأَن تَصُومُواْ خَيۡرٞ لَّكُمۡ إِن كُنتُمۡ تَعۡلَمُونَ
[Observing Saum (fasts)] for a fixed number of days, but if any of you is ill or on a journey, the same number (should be made up) from other days. And as for those who can fast with difficulty, (e.g. an old man, etc.), they have (a choice either to fast or) to feed a Miskin (poor person) (for every day). But whoever does good of his own accord, it is better for him. And that you fast, it is better for you if only you know.
Chapter 2, Verse 197, The Cow
سُوۡرَةُ البَقَرَة
ٱلۡحَجُّ أَشۡهُرٞ مَّعۡلُومَٰتٞۚ فَمَن فَرَضَ فِيهِنَّ ٱلۡحَجَّ فَلَا رَفَثَ وَلَا فُسُوقَ وَلَا جِدَالَ فِي ٱلۡحَجِّۗ وَمَا تَفۡعَلُواْ مِنۡ خَيۡرٖ يَعۡلَمۡهُ ٱللَّهُۗ وَتَزَوَّدُواْ فَإِنَّ خَيۡرَ ٱلزَّادِ ٱلتَّقۡوَىٰۖ وَٱتَّقُونِ يَٰٓأُوْلِي ٱلۡأَلۡبَٰبِ
The Hajj (pilgrimage) is (in) the well-known (lunar year) months (i.e. the 10th month, the 11th month and the first ten days of the 12th month of the Islamic calendar, i.e. two months and ten days). So whosoever intends to perform Hajj therein by assuming Ihram), then he should not have sexual relations (with his wife), nor commit sin, nor dispute unjustly during the Hajj. And whatever good you do, (be sure) Allah knows it. And take a provision (with you) for the journey, but the best provision is At-Taqwa (piety, righteousness, etc.). So fear Me, O men of understanding!
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 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 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).
