وَعَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا تُكْثِرُوا الْكَلَامَ بِغَيْرِ ذِكْرِ اللَّهِ فَإِنَّ كَثْرَةَ الْكَلَامِ بِغَيْرِ ذِكْرِ اللَّهِ قَسْوَةٌ لِلْقَلْبِ وَإِنَّ أَبْعَدَ النَّاسِ مِنَ اللَّهِ الْقَلْبُ الْقَاسِي» . رَوَاهُ التِّرْمِذِيّ

Ibn ‘Umar (may God be pleased with them both) reported that the Messenger of God (peace be upon him) said: ‘Do not speak at length without remembering God, for much speech without remembrance of God hardens the heart. The people farthest from God are those with hard hearts.’ Al-Tirmidhi transmitted it. The Arabic source marks it as not studied by al-Albani.
