Arabic (Original)
حَدَّثَنَا ابْنُ نُمَيْرٍ حَدَّثَنَا الْأَعْمَشُ عَنْ إِبْرَاهِيمَ عَنِ الْأَسْوَدِ قَالَ دَخَلْتُ أَنَا وَعَلْقَمَةُ عَلَى عَبْدِ اللَّهِ بْنِ مَسْعُودٍ فَقَالَ إِذَا رَكَعَ أَحَدُكُمْ فَلْيُفْرِشْ ذِرَاعَيْهِ فَخِذَيْهِ فَكَأَنِّي أَنْظُرُ إِلَى اخْتِلَافِ أَصَابِعِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي الصَّلَاةِ.
English Translation
The Messenger of Allah (peace be upon him) said: 'Beware of lying, for lying leads to wickedness, and wickedness leads to the Fire. A man keeps lying and pursuing lies until he is written with Allah as a liar. And adhere to truthfulness, for truthfulness leads to righteousness, and righteousness leads to Paradise. A man keeps being truthful and pursuing truthfulness until he is written with Allah as truthful.'
