Hadith 23: Purification is Half of Faith
Abu Malik Al-Ashari reported: The Messenger of Allah, peace and blessings be upon him, said:
الطُّهُورُ شَطْرُ الْإِيمَانِ وَالْحَمْدُ لِلَّهِ تَمْلَأُ الْمِيزَانَ وَسُبْحَانَ اللَّهِ وَالْحَمْدُ لِلَّهِ تَمْلَآَنِ أَوْ تَمْلَأُ مَا بَيْنَ السَّمَاوَاتِ وَالْأَرْضِ وَالصَّلَاةُ نُورٌ وَالصَّدَقَةُ بُرْهَانٌ وَالصَّبْرُ ضِيَاءٌ وَالْقُرْآنُ حُجَّةٌ لَكَ أَوْ عَلَيْكَ كُلُّ النَّاسِ يَغْدُو فَبَايِعٌ نَفْسَهُ فَمُعْتِقُهَا أَوْ مُوبِقُهَا
Purity is half of faith, and the praise of Allah fills the scale. Glorification and praise fill up what is between the heavens and the earth. Prayer is a light, charity is a proof, and patience is illumination. The Quran is a proof for you or against you. All people go out early in the morning and sell themselves, either setting themselves free or destroying themselves.
