حَدَّثَنَا أَحْمَدُ بْنُ مَنِيعٍ، حَدَّثَنَا مَرْوَانُ بْنُ مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ ذَرٍّ، عَنْ يُسَيْعٍ، عَنِ النُّعْمَانِ بْنِ بَشِيرٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم 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 .

Ahmad ibn Mani‘ narrated to us: Marwan ibn Mu‘awiyah narrated to us, from al-A‘mash, from Dharr, from Yusay‘, from al-Nu‘man ibn Bashir, from the Prophet, who said: ‘Supplication is worship.’ Then he recited: ‘Your Lord has said, “Call upon Me; I will answer you.” Those who are too proud to worship Me will enter Hell, humbled’ (40:60). This hadith is hasan sahih. Mansur and al-A‘mash also narrated it from Dharr, and we know it only through Dharr’s narration. He is Dharr ibn ‘Abdullah al-Hamdani, a trustworthy narrator and the father of ‘Umar ibn Dharr.
Notes and open questions — unreviewed
The Qur’anic quotation explicitly connects supplication with worship. The compiler identifies Dharr ibn ‘Abdullah al-Hamdani, comments on his reliability, and says Mansur and al-A‘mash transmitted it from him.
