"لا يَسْتَقيمُ إِيمَانُ عَبْد حَتَّى يسْتَقِيمَ قَلْبُهُ، وَلا يَسْتَقِيمُ قَلْبُهُ حَتَّى يَسْتَقِيمَ لِسَانُهُ، وَلا يَدْخُلُ الجَنَّةَ حَتَّى يَأمَنَ جَارُهُ بَوَائِقَهُ".

the Messenger of Allah ﷺ said, "The faith of a servant is not upright until his heart is upright; and his heart is not upright until his tongue is upright; and a man will not enter Paradise if his neighbor is not secure from his evil."  

أحمد:١٣٠٤٨ – حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ قَالَ أَخْبَرَنِي عَلِيُّ بْنُ مَسْعَدَةَ الْبَاهِلِيُّ قَالَ حَدَّثَنَا قَتَادَةُ عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ

قَالَ رَسُولُ اللهِ ﷺ «لَا يَسْتَقِيمُ إِيمَانُ عَبْدٍ حَتَّى يَسْتَقِيمَ قَلْبُهُ؛ وَلَا يَسْتَقِيمُ قَلْبُهُ حَتَّى يَسْتَقِيمَ لِسَانُهُ؛ وَلَا يَدْخُلُ الْجَنَّةَ رَجُلٌ لَا يَأْمَنُ جَارُهُ بَوَائِقَهُ۔»
