حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنْ مَنْصُورٍ، عَنْ ذَرٍّ، عَنْ يُسَيْعٍ الْحَضْرَمِيِّ، عَنِ النُّعْمَانِ بْنِ بَشِيرٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ الدُّعَاءُ هُوَ الْعِبَادَةُ ‏{‏ قَالَ رَبُّكُمُ ادْعُونِي أَسْتَجِبْ لَكُمْ ‏}‏ ‏"‏ ‏.‏

'Asma daughter of Yazid reported the Prophet (ﷺ) as saying

"Allah's Greatest Names is in these two verses: "And your Ilaah (God) is One Ilaah (God), none has the right to be worshipped but He, the Ever-Merciful, the Mercy-Giving' and the beginning of Surah Al 'Imran, "A.L.M Allah, there is no deity but He, the Living, the Eternal."
