suyuti:25799a

“None servant of Allah will [truly] believe until his tongue and heart [are at balance], and until he keeps neighbor safe through his wickedness, and his speech does not contradict his action.”  

Ibn Najjār
السيوطي:٢٥٧٩٩aعن أَنس

"لا يُؤْمِنُ عَبْدٌ حَتَّى يَكُونَ لِسَانُهُ وَقَلبُهُ سَوَاءً، وَحَتَّى يَأمَنَ جَارُهُ بَوَائِقَهُ، وَلا يُخَالِفُ قَوْلُهُ فِعْلَهُ"  

لابن النجار
