حَدَّثَنَا عَلِيُّ بْنُ حُجْرٍ، أَخْبَرَنَا الْوَلِيدُ بْنُ مُسْلِمٍ، عَنِ ابْنِ لَهِيعَةَ، عَنْ عُبَيْدِ اللَّهِ بْنِ أَبِي جَعْفَرٍ، عَنْ أَبَانَ بْنِ صَالِحٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " الدُّعَاءُ مُخُّ الْعِبَادَةِ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ غَرِيبٌ مِنْ هَذَا الْوَجْهِ لاَ نَعْرِفُهُ إِلاَّ مِنْ حَدِيثِ ابْنِ لَهِيعَةَ .

‘Ali ibn Hujr narrated to us: al-Walid ibn Muslim informed us, from Ibn Lahi‘ah, from ‘Ubaydullah ibn Abi Ja‘far, from Aban ibn Salih, from Anas ibn Malik, from the Prophet, who said: ‘Supplication is the core of worship.’ Abu ‘Isa said: This hadith is gharib by this route; we know it only through the narration of Ibn Lahi‘ah.
