Importance of Prayer in Islam

ذَ‌ٰلِكَ الْكِتَابُ لَا رَيْبَ ۛ فِيهِ ۛ هُدًى لِلْمُتَّقِينَ الَّذِينَ يُؤْمِنُونَ بِالْغَيْبِ وَيُقِيمُونَ الصَّلَاةَ وَمِمَّا رَزَقْنَاهُمْ يُنْفِقُونَ

This is the Book in which there is no doubt, a guidance for those who have Taqwa; who believe in the unseen, and who establish Salah, and spend out of what we have provided for them

~Surah Baqarah 2: 2-3

وَالْمُؤْمِنُونَ وَالْمُؤْمِنَاتُ بَعْضُهُمْ أَوْلِيَاءُ بَعْضٍ ۚ يَأْمُرُونَ بِالْمَعْرُوفِ وَيَنْهَوْنَ عَنِ الْمُنْكَرِ وَيُقِيمُونَ الصَّلَاةَ وَيُؤْتُونَ الزَّكَاةَ وَيُطِيعُونَ اللَّهَ وَرَسُولَهُ ۚ أُولَـٰئِكَ سَيَرْحَمُهُمُ اللَّهُ ۗ إِنَّ اللَّهَ عَزِيزٌ حَكِيمٌ

The believers, men and women, are protecting friends of one another; they enjoin good and forbid evil, and they establish Salah, and give Zakah, and obey Allah and His Messenger. Allah will have His Mercy on them, and surely, Allah is All-Mighty, All-Wise.

~Surah Tawba 9: 71

فَمَا أُوتِيتُمْ مِنْ شَيْءٍ فَمَتَاعُ الْحَيَاةِ الدُّنْيَا ۖ وَمَا عِنْدَ اللَّهِ خَيْرٌ وَأَبْقَىٰ لِلَّذِينَ آمَنُوا وَعَلَىٰ رَبِّهِمْ يَتَوَكَّلُونَ وَالَّذِينَ يَجْتَنِبُونَ كَبَائِرَ الْإِثْمِ وَالْفَوَاحِشَ وَإِذَا مَا غَضِبُوا هُمْ يَغْفِرُونَ وَالَّذِينَ اسْتَجَابُوا لِرَبِّهِمْ وَأَقَامُوا الصَّلَاةَ وَأَمْرُهُمْ شُورَىٰ بَيْنَهُمْ وَمِمَّا رَزَقْنَاهُمْ يُنْفِقُونَ

So whatever you have been given is but (a passing) enjoyment for this worldly life, but that which is with Allah is better and more lasting for those who believe and put their trust in their Lord. And those who avoid the great sins and lewdness, and when they are angry, they forgive. And those who answer the Call of their Lord, and perform the Salah, and who conduct their affairs by mutual consultation, and who spend of what We have bestowed on them.

~Surah Ash-Shura 42:36-38

إِنَّ الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ وَأَقَامُوا الصَّلَاةَ وَآتَوُا الزَّكَاةَ لَهُمْ أَجْرُهُمْ عِنْدَ رَبِّهِمْ وَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ

Truly, those who believe and do righteous deeds, and perform Salah, and give Zakah, they will have their reward with their Lord. On them shall be no fear, nor shall they grieve.

~Surah Baqarah 2:277

فَإِذَا قَضَيْتُمُ الصَّلَاةَ فَاذْكُرُوا اللَّهَ قِيَامًا وَقُعُودًا وَعَلَىٰ جُنُوبِكُمْ ۚ فَإِذَا اطْمَأْنَنْتُمْ فَأَقِيمُوا الصَّلَاةَ ۚ إِنَّ الصَّلَاةَ كَانَتْ عَلَى الْمُؤْمِنِينَ كِتَابًا مَوْقُوتًا

When have finished performing the Salah, remember Allah standing, sitting, and reclining, but when you are free from danger, perform the Salah. Surely, Salah is enjoined on the believers at fixed times.

~Surah Nisaa 4:103

وَأَقِيمُوا الصَّلَاةَ وَآتُوا الزَّكَاةَ وَارْكَعُوا مَعَ الرَّاكِعِينَ

And establish Salah and give Zakah, and bow down (in worship) along with those who bow down (in worship)

~Surah Baqarah 2:43

حَافِظُوا عَلَى الصَّلَوَاتِ وَالصَّلَاةِ الْوُسْطَىٰ وَقُومُوا لِلَّهِ قَانِتِينَ

Guard strictly the Salah, especially the middle Salah. And stand before Allah with obedience.

~Surah Baqarah 2:238

وَاسْتَعِينُوا بِالصَّبْرِ وَالصَّلَاةِ ۚ وَإِنَّهَا لَكَبِيرَةٌ إِلَّا عَلَى الْخَاشِعِينَ

Seek help through patience and Salah; truly it is extremely difficult except for the humble true believers.

~Surah Baqarah 2:45

يَا أَيُّهَا الَّذِينَ آمَنُوا اسْتَعِينُوا بِالصَّبْرِ وَالصَّلَاةِ ۚ إِنَّ اللَّهَ مَعَ الصَّابِرِينَ

Oh you who believe! Seek help through patience and Salah. Truly, Allah is with those who are patient.

~Surah Baqarah 2:153

يَا أَيُّهَا الَّذِينَ آمَنُوا إِذَا نُودِيَ لِلصَّلَاةِ مِنْ يَوْمِ الْجُمُعَةِ فَاسْعَوْا إِلَىٰ ذِكْرِ اللَّهِ وَذَرُوا الْبَيْعَ ۚ ذَ‌ٰلِكُمْ خَيْرٌ لَكُمْ إِنْ كُنْتُمْ تَعْلَمُونَ فَإِذَا قُضِيَتِ الصَّلَاةُ فَانْتَشِرُوا فِي الْأَرْضِ وَابْتَغُوا مِنْ فَضْلِ اللَّهِ وَاذْكُرُوا اللَّهَ كَثِيرًا لَعَلَّكُمْ تُفْلِحُونَ

Oh you who believe! When the call is made for the Salah on Friday, come to the remembrance of Allah, and leave off business. That is better for you, if you only knew! And when the Salah has ended, you may disperse through the land, and seek the Bounty of Allah, and remember Allah much so that you may be successful.

~Surah Jumuah 62:09-10

اُتۡلُ مَاۤ اُوۡحِيَ اِلَيۡکَ مِنَ الۡکِتٰبِ وَاَقِمِ الصَّلٰوةَ ؕ اِنَّ الصَّلٰوةَ تَنۡہٰي عَنِ الۡفَحۡشَآءِ وَالۡمُنۡکَرِ ؕ وَلَذِکۡرُ اللّٰہِ اَکۡبَرُ ؕ وَاللّٰہُ يَعۡلَمُ مَا تَصۡنَعُوۡنَ

Recite that which has been revealed to thee of the Book, and observe Prayer. Surely, Prayer restrains [one] from indecency and manifest evil, and remembrance of Allah indeed is the greatest [virtue]. And Allah knows what you do.

~Surah al-'Ankabut, Ch.29: V.46
