حَدَّثَنَا هَنَّادٌ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ ذَرٍّ، عَنْ يُسَيْعٍ الْكِنْدِيِّ، عَنِ النُّعْمَانِ بْنِ بَشِيرٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم فِي قَوْلِهِ : (وَقَالَ رَبُّكُمُ ادْعُونِي أَسْتَجِبْ لَكُمْ ) قَالَ " الدُّعَاءُ هُوَ الْعِبَادَةُ " . وَقَرَأَ :( وَقَالَ رَبُّكُمُ ادْعُونِي أَسْتَجِبْ لَكُمْ ) إِلَى قَوْلِهِ ( دَاخِرِينَ ) . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
from the Prophet (ﷺ) regarding Allah's saying: Your Lord said: Invoke Me, I shall respond to you (40:60, it appears that the author intended to apply it to Al-Baqarah 2:186). - he said: "The supplication is the worship." And he recited: 'Your Lord said: Invoke Me, I shall respond to you.' up to His saying: 'in humiliation.'"
