حَٰفِظُوا۟ عَلَى ٱلصَّلَوَٰتِ وَٱلصَّلَوٰةِ ٱلْوُسْطَىٰ وَقُومُوا۟ لِلَّهِ قَٰنِتِينَ ﴿٢٣٨﴾
Maintain with care the [obligatory] prayers and [in particular] the middle prayer and stand before Allah, devoutly obedient.
Prayer (Salah)
The five daily prayers are a pillar of Islam and the first thing that a person will be asked about on the Day of Judgement. Allah says that prayer is obligatory upon the believers at fixed times (4:103). The Prophet ﷺ said that Islam is built on five, and prayer is one of them.
The four Sunni schools agree on the main ruling above and differ in these points. No school is preferred here.
حَٰفِظُوا۟ عَلَى ٱلصَّلَوَٰتِ وَٱلصَّلَوٰةِ ٱلْوُسْطَىٰ وَقُومُوا۟ لِلَّهِ قَٰنِتِينَ ﴿٢٣٨﴾
Maintain with care the [obligatory] prayers and [in particular] the middle prayer and stand before Allah, devoutly obedient.
فَإِذَا قَضَيْتُمُ ٱلصَّلَوٰةَ فَٱذْكُرُوا۟ ٱللَّهَ قِيَٰمًۭا وَقُعُودًۭا وَعَلَىٰ جُنُوبِكُمْ ۚ فَإِذَا ٱطْمَأْنَنتُمْ فَأَقِيمُوا۟ ٱلصَّلَوٰةَ ۚ إِنَّ ٱلصَّلَوٰةَ كَانَتْ عَلَى ٱلْمُؤْمِنِينَ كِتَٰبًۭا مَّوْقُوتًۭا ﴿١٠٣﴾
And when you have completed the prayer, remember Allah standing, sitting, or [lying] on your sides. But when you become secure, re-establish [regular] prayer. Indeed, prayer has been decreed upon the believers a decree of specified times.
إِنَّنِىٓ أَنَا ٱللَّهُ لَآ إِلَٰهَ إِلَّآ أَنَا۠ فَٱعْبُدْنِى وَأَقِمِ ٱلصَّلَوٰةَ لِذِكْرِىٓ ﴿١٤﴾
Indeed, I am Allah. There is no deity except Me, so worship Me and establish prayer for My remembrance.
The point of the hadith: Islam is built on five: the testimony of faith, prayer, zakat, Hajj and fasting Ramadan.
حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى، قَالَ أَخْبَرَنَا حَنْظَلَةُ بْنُ أَبِي سُفْيَانَ، عَنْ عِكْرِمَةَ بْنِ خَالِدٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " بُنِيَ الإِسْلاَمُ عَلَى خَمْسٍ شَهَادَةِ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ، وَإِقَامِ الصَّلاَةِ، وَإِيتَاءِ الزَّكَاةِ، وَالْحَجِّ، وَصَوْمِ رَمَضَانَ ".
The point of the hadith: The five prayers are like a river at a door in which a person bathes five times a day: no dirt would remain on him. In the same way they wipe away sins.
حَدَّثَنَا إِبْرَاهِيمُ بْنُ حَمْزَةَ، قَالَ حَدَّثَنِي ابْنُ أَبِي حَازِمٍ، وَالدَّرَاوَرْدِيُّ، عَنْ يَزِيدَ، عَنْ مُحَمَّدِ بْنِ إِبْرَاهِيمَ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّهُ سَمِعَ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " أَرَأَيْتُمْ لَوْ أَنَّ نَهَرًا بِبَابِ أَحَدِكُمْ، يَغْتَسِلُ فِيهِ كُلَّ يَوْمٍ خَمْسًا، مَا تَقُولُ ذَلِكَ يُبْقِي مِنْ دَرَنِهِ ". قَالُوا لاَ يُبْقِي مِنْ دَرَنِهِ شَيْئًا. قَالَ " فَذَلِكَ مِثْلُ الصَّلَوَاتِ الْخَمْسِ، يَمْحُو اللَّهُ بِهَا الْخَطَايَا ".
The point of the hadith: The deed dearest to Allah is the prayer at its early fixed time, then kindness to parents.
حَدَّثَنَا أَبُو الْوَلِيدِ، هِشَامُ بْنُ عَبْدِ الْمَلِكِ قَالَ حَدَّثَنَا شُعْبَةُ، قَالَ الْوَلِيدُ بْنُ الْعَيْزَارِ أَخْبَرَنِي قَالَ سَمِعْتُ أَبَا عَمْرٍو الشَّيْبَانِيَّ، يَقُولُ حَدَّثَنَا صَاحِبُ، هَذِهِ الدَّارِ وَأَشَارَ إِلَى دَارِ عَبْدِ اللَّهِ قَالَ سَأَلْتُ النَّبِيَّ صلى الله عليه وسلم أَىُّ الْعَمَلِ أَحَبُّ إِلَى اللَّهِ قَالَ " الصَّلاَةُ عَلَى وَقْتِهَا ". قَالَ ثُمَّ أَىُّ قَالَ " ثُمَّ بِرُّ الْوَالِدَيْنِ ". قَالَ ثُمَّ أَىُّ قَالَ " الْجِهَادُ فِي سَبِيلِ اللَّهِ ". قَالَ حَدَّثَنِي بِهِنَّ وَلَوِ اسْتَزَدْتُهُ لَزَادَنِي.
