الترمذي:٣٣٧٢حَدَّثَنَا أَحْمَدُ بْنُ مَنِيعٍ حَدَّثَنَا مَرْوَانُ بْنُ مُعَاوِيَةَ عَنِ الأَعْمَشِ عَنْ ذَرٍّ عَنْ يُسَيْعٍ عَنِ النُّعْمَانِ بْنِ بَشِيرٍ

عَنِ النَّبِيِّ ﷺ قَالَ الدُّعَاءُ هُوَ الْعِبَادَةُ ثُمَّ قَرَأََ (وقالَ رَبُّكُمُ ادْعُونِي أَسْتَجِبْ لَكُمْ إِنَّ الَّذِينَ يَسْتَكْبِرُونَ عَنْ عِبَادَتِي سَيَدْخُلُونَ جَهَنَّمَ دَاخِرِينَ ) قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ وَقَدْ رَوَاهُ مَنْصُورٌ وَالأَعْمَشُ عَنْ ذَرٍّ وَلاَ نَعْرِفُهُ إِلاَّ مِنْ حَدِيثِ ذَرٍّ هُوَ ذَرُّ بْنُ عَبْدِ اللَّهِ الْهَمْدَانِيُّ ثِقَةٌ وَالِدُ عُمَرَ بْنِ ذَرٍّ
