Malik recorded that Abu Hurayrah said that the Messenger of Allah said,

«إِذَا تَوَضَّأَ الْعَبْدُ الْمُسْلِمُ أَوِ الْمُؤْمِنُ فَغَسَلَ وَجْهَهُ، خَرَجَ مِنْ وَجْهِهِ، كُلُّ خَطِيئَةٍ نَظَرَ إِلَيْهَا بِعَيْنَيْهِ مَعَ الْمَاءِ أَوْ مَعَ آخِرِ قَطْرِ الْمَاءِ، فَإِذَا غَسَلَ يَدَيهِ خَرَجَ مِنْ يَدَيْهِ كُلُّ خَطِيئَةٍ بَطَشَتْهَا يَدَاهُ مَعَ الْمَاءِ أَوْ مَعَ آخِرِ قَطْرِ الْمَاءِ، فَإِذَا غَسَلَ رِجْلَيْهِ خَرَجَتْ كُلُّ خَطِيئةٍ مَشَتْهَا رِجْلَاهُ مَعَ الْمَاءِ أَوْ مَعَ آخِرِ قَطْرِ الْمَاءِ، حَتَّى يَخْرُجَ نَقِيًّا مِنَ الذُّنُوب»

(When the Muslim or the believing servant performs Wudu' and washes his face, every sin that he looked at with his eyes will depart from his face with the water, or with the last drop of water. When he washes his hands, every sin that his hands committed will depart from his hands with the water, or with the last drop of water. When he washes his feet, every sin to which his feet took him will depart with the water, or with the last drop of water. Until, he ends up sinless.) Muslim also recorded it. Muslim recorded that Abu Malik Al-Ash`ari said that the Messenger of Allah said,

«الطُّهُور شَطْرُ الْإِيمَانِ، وَالْحَمْدُ للهِ تَمْلَأُ الْمِيزَانَ، وَسُبْحَانَ اللهِ وَاللهُ أَكْبَرُ تَمْلَأُ مَا بَيْنَ السَّمَاءِ وَالْأَرْضِ، وَالصَّوْمُ جُنَّةٌ، وَالصَّبْرُ ضِيَاءٌ، وَالصدَقَةُ بُرْهَانٌ، وَالقُرْآنُ حُجَّةٌ لَكَ أَوْ عَلَيْكَ، كُلُّ النَّاسِ يَغْدُو، فَبَائِعٌ نَفْسَهُ فَمُعْتِقُهَا أَوْ مُوبِقُهَا»

(Purity is half of faith and Al-Hamdu Lillah (all the thanks are due to Allah) fills the Mizan (the Scale). And Subhan Allah and Allahu Akbar (all praise is due to Allah, and Allah is the Most Great) fills what is between the heaven and earth. As-Sawm (the fast) is a Junnah (a shield), Sabr (patience) is a light, Sadaqah (charity) is evidence (of faith) and the Qur'an is proof for, or against you. Every person goes out in the morning and ends up selling himself, he either frees his soul or destroys it.) Muslim recorded that Ibn `Umar said that the Messenger of Allah said,

«لَا يَقْبَلُ اللهُ صَدَقَةً مِنْ غُلُولٍ، وَلَا صَلَاةً بِغَيْرِ طُهُور»

(Allah does not accept charity from one who commits Ghulul, or prayer without purity.)

﴿وَاذْكُرُواْ نِعْمَةَ اللَّهِ عَلَيْكُمْ وَمِيثَـقَهُ الَّذِى وَاثَقَكُم بِهِ إِذْ قُلْتُمْ سَمِعْنَا وَأَطَعْنَا وَاتَّقُواْ اللَّهَ إِنَّ اللَّهَ عَلِيمٌ بِذَاتِ الصُّدُورِ - يَـأَيُّهَآ الَّذِينَ ءَامَنُواْ كُونُواْ قَوَّامِينَ للَّهِ شُهَدَآءَ بِالْقِسْطِ وَلاَ يَجْرِمَنَّكُمْ شَنَآنُ قَوْمٍ عَلَى أَلاَّ تَعْدِلُواْ اعْدِلُواْ هُوَ أَقْرَبُ لِلتَّقْوَى وَاتَّقُواْ اللَّهَ إِنَّ اللَّهَ خَبِيرٌ بِمَا تَعْمَلُونَ - وَعَدَ اللَّهُ الَّذِينَ ءَامَنُواْ وَعَمِلُواْ الصَّـلِحَـتِ لَهُم مَّغْفِرَةٌ وَأَجْرٌ عَظِيمٌ - وَالَّذِينَ كَفَرُواْ وَكَذَّبُواْ بِـَايَـتِنَآ أُوْلَـئِكَ أَصْحَـبُ الْجَحِيمِ - يَـأَيُّهَآ الَّذِينَ ءَامَنُواْ اذْكُرُواْ نِعْمَةَ اللَّهِ عَلَيْكُمْ إِذْ هَمَّ قَوْمٌ أَن يَبْسُطُواْ إِلَيْكُمْ أَيْدِيَهُمْ فَكَفَّ أَيْدِيَهُمْ عَنكُمْ وَاتَّقُواْ اللَّهَ وَعَلَى اللَّهِ فَلْيَتَوَكَّلِ الْمُؤْمِنُونَ ﴾

(7. And remember Allah's favor to you and His covenant with which He bound you when you said: "We hear and we obey.'' And have Taqwa of Allah. Verily, Allah is All-Knower of that which is in the breasts.) (8. O you who believe! Stand out firmly for Allah as just witnesses; and let not the enmity and hatred of others make you avoid justice. Be just, that is nearer to Taqwa; and have Taqwa of Allah. Verily, Allah is Well-Acquainted with what you do.) (9. Allah has promised those who believe and do deeds of righteousness, that for them there is forgiveness and a great reward (i.e. Paradise).) (10. And they who disbelieve and deny Our Ayat are those who will be the dwellers of the Hell-fire.) (11. O you who believe! Remember the favor of Allah unto you when some people desired (made a plan) to stretch out their hands against you, but (Allah) held back their hands from you. So have Taqwa of Allah. And in Allah let the believers put their trust.)
