Arabic (Original)
حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ قَالَ أَخْبَرَنِي عَلِيُّ بْنُ مَسْعَدَةَ الْبَاهِلِيُّ قَالَ حَدَّثَنَا قَتَادَةُ عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَا يَسْتَقِيمُ إِيمَانُ عَبْدٍ حَتَّى يَسْتَقِيمَ قَلْبُهُ وَلَا يَسْتَقِيمُ قَلْبُهُ حَتَّى يَسْتَقِيمَ لِسَانُهُ وَلَا يَدْخُلُ رَجُلٌ الْجَنَّةَ لَا يَأْمَنُ جَارُهُ بَوَائِقَهُ.
English Translation
Zayd ibn al-Hubab told us, he said: 'Ali ibn Mas'adah al-Bahili informed me, he said: Qatadah told us, from Anas ibn Malik, who said, "The Messenger of Allah, peace and blessings be upon him, said, 'A servant's faith is not upright until his heart is upright, and his heart is not upright until his tongue is upright. And no man enters Paradise whose neighbor is not safe from his harmful conduct.'"
