Chapter 2, Verse 142, The Cow
سُوۡرَةُ البَقَرَة
۞سَيَقُولُ ٱلسُّفَهَآءُ مِنَ ٱلنَّاسِ مَا وَلَّىٰهُمۡ عَن قِبۡلَتِهِمُ ٱلَّتِي كَانُواْ عَلَيۡهَاۚ قُل لِّلَّهِ ٱلۡمَشۡرِقُ وَٱلۡمَغۡرِبُۚ يَهۡدِي مَن يَشَآءُ إِلَىٰ صِرَٰطٖ مُّسۡتَقِيمٖ
The fools (pagans, hypocrites, and Jews) among the people will say, "What has turned them (Muslims) from their Qiblah [prayer direction (towards Jerusalem)] to which they were used to face in prayer." Say, (O Muhammad ﷺ) "To Allah belong both, east and the west. He guides whom He wills to a Straight Way."
Chapter 2, Verse 145, The Cow
سُوۡرَةُ البَقَرَة
وَلَئِنۡ أَتَيۡتَ ٱلَّذِينَ أُوتُواْ ٱلۡكِتَٰبَ بِكُلِّ ءَايَةٖ مَّا تَبِعُواْ قِبۡلَتَكَۚ وَمَآ أَنتَ بِتَابِعٖ قِبۡلَتَهُمۡۚ وَمَا بَعۡضُهُم بِتَابِعٖ قِبۡلَةَ بَعۡضٖۚ وَلَئِنِ ٱتَّبَعۡتَ أَهۡوَآءَهُم مِّنۢ بَعۡدِ مَا جَآءَكَ مِنَ ٱلۡعِلۡمِ إِنَّكَ إِذٗا لَّمِنَ ٱلظَّٰلِمِينَ
And even if you were to bring to the people of the Scripture (Jews and Christians) all the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), they would not follow your Qiblah (prayer direction), nor are you going to follow their Qiblah (prayer direction). And they will not follow each other's Qiblah (prayer direction). Verily, if you follow their desires after that which you have received of knowledge (from Allah), then indeed you will be one of the Zalimun (polytheists, wrong-doers, etc.).
Chapter 17, Verse 79, The night journey
سورة الإسراء
وَمِنَ ٱلَّيۡلِ فَتَهَجَّدۡ بِهِۦ نَافِلَةٗ لَّكَ عَسَىٰٓ أَن يَبۡعَثَكَ رَبُّكَ مَقَامٗا مَّحۡمُودٗا
And in some parts of the night (also) offer the Salat (prayer) with it (i.e. recite the Quran in the prayer), as an additional prayer (Tahajjud optional prayer Nawafil) for you (O Muhammad ﷺ). It may be that your Lord will raise you to Maqaman Mahmuda (a station of praise and glory, i.e. the highest degree in Paradise!).
Chapter 19, Verse 31, Mary
سورة مريم
وَجَعَلَنِي مُبَارَكًا أَيۡنَ مَا كُنتُ وَأَوۡصَٰنِي بِٱلصَّلَوٰةِ وَٱلزَّكَوٰةِ مَا دُمۡتُ حَيّٗا
"And He has made me blessed wheresoever I be, and has enjoined on me Salat (prayer), and Zakat, as long as I live."
Chapter 62, Verse 9, The congregation, Friday
سورة الجمعة
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِذَا نُودِيَ لِلصَّلَوٰةِ مِن يَوۡمِ ٱلۡجُمُعَةِ فَٱسۡعَوۡاْ إِلَىٰ ذِكۡرِ ٱللَّهِ وَذَرُواْ ٱلۡبَيۡعَۚ ذَٰلِكُمۡ خَيۡرٞ لَّكُمۡ إِن كُنتُمۡ تَعۡلَمُونَ
O you who believe (Muslims)! When the call is proclaimed for the Salat (prayer) on the day of Friday (Jumu'ah prayer), come to the remembrance of Allah [Jumu'ah religious talk (Khutbah) and Salat (prayer)] and leave off business (and every other thing), that is better for you if you did but know!
Chapter 77, Verse 48, The emissaries
سورة المرسلات
وَإِذَا قِيلَ لَهُمُ ٱرۡكَعُواْ لَا يَرۡكَعُونَ
And when it is said to them: "Bow down yourself (in prayer)!" They bow not down (offer not their prayers).
Chapter 94, Verse 7, Solace
سورة الشرح
فَإِذَا فَرَغۡتَ فَٱنصَبۡ
So when you have finished (from your occupation), then stand up for Allah's worship (i.e. stand up for prayer).
Chapter 107, Verse 5, Alms Giving
سورة الماعون
ٱلَّذِينَ هُمۡ عَن صَلَاتِهِمۡ سَاهُونَ
Who delay their Salat (prayer) from their stated fixed times,
Chapter 108, Verse 2, Abundance
سورة الكوثر
فَصَلِّ لِرَبِّكَ وَٱنۡحَرۡ
Therefore turn in prayer to your Lord and sacrifice (to Him only).
Chapter 4, Verse 103, The Women
سورة النساء
فَإِذَا قَضَيۡتُمُ ٱلصَّلَوٰةَ فَٱذۡكُرُواْ ٱللَّهَ قِيَٰمٗا وَقُعُودٗا وَعَلَىٰ جُنُوبِكُمۡۚ فَإِذَا ٱطۡمَأۡنَنتُمۡ فَأَقِيمُواْ ٱلصَّلَوٰةَۚ إِنَّ ٱلصَّلَوٰةَ كَانَتۡ عَلَى ٱلۡمُؤۡمِنِينَ كِتَٰبٗا مَّوۡقُوتٗا
When you have finished As-Salat (the prayer - congregational), remember Allah standing, sitting down, and lying down on your sides, but when you are free from danger, perform As-Salat (Iqamat-as- Salat). Verily, the prayer is enjoined on the believers at fixed hours.
