Prayer is light

Purity is half of faith, and the prayer is a light.

Narrated by Abu Malik al-Ash'ari

Purity is half of faith. Alhamdulillah fills the scale, and SubhanAllah and Alhamdulillah fill what is between the heavens and the earth. Prayer is light, charity is proof, patience is brightness, and the Qur'an is an argument for you or against you.

Sahih Muslim 223

The hadith in Arabic نص الحديث

الطُّهُورُ شَطْرُ الإِيمَانِ وَالْحَمْدُ لِلَّهِ تَمْلأُ الْمِيزَانَ ‏.‏ وَسُبْحَانَ اللَّهِ وَالْحَمْدُ لِلَّهِ تَمْلآنِ - أَوْ تَمْلأُ - مَا بَيْنَ السَّمَوَاتِ وَالأَرْضِ وَالصَّلاَةُ نُورٌ وَالصَّدَقَةُ بُرْهَانٌ وَالصَّبْرُ ضِيَاءٌ وَالْقُرْآنُ حُجَّةٌ لَكَ أَوْ عَلَيْكَ كُلُّ النَّاسِ يَغْدُو فَبَائِعٌ نَفْسَهُ فَمُعْتِقُهَا أَوْ مُوبِقُهَا
