Al-Adab Al-Mufrad, Book 53, Hadith 1255 (In-Book) ⓘ

Mu'awiya ibn Qurra said, "When Iyas was born to me, I invited a group of the Companions of the Prophet, may Allah bless him and grant him peace, and I fed them and they made supplication. I said, 'You have made supplication, so may Allah bless you for your supplication. If I make supplication, then you say, "Amen".' He went on, 'I made a lot of supplication for him for his deen, his intellect and things like that.' He added, 'I still recognise the supplication of that day in him."

حَدَّثَنَا مُحَمَّدٌ، قَالَ‏:‏ أَخْبَرَنَا عَبْدُ اللهِ، قَالَ‏:‏ أَخْبَرَنَا حَزْمٌ قَالَ‏:‏ سَمِعْتُ مُعَاوِيَةَ بْنَ قُرَّةَ يَقُولُ‏:‏ لَمَّا وُلِدَ لِي إِيَاسٌ دَعَوْتُ نَفَرًا مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم فَأَطْعَمْتُهُمْ، فَدَعَوْا، فَقُلْتُ‏:‏ إِنَّكُمْ قَدْ دَعَوْتُمْ فَبَارَكَ اللَّهُ لَكُمْ فِيمَا دَعَوْتُمْ، وَإِنِّي إِنْ أَدْعُو بِدُعَاءٍ فَأَمِّنُوا، قَالَ‏:‏ فَدَعَوْتُ لَهُ بِدُعَاءٍ كَثِيرٍ فِي دِينِهِ وَعَقْلِهِ وَكَذَا، قَالَ‏:‏ فَإِنِّي لَأَتَعَرَّفُ فِيهِ دُعَاءَ يَوْمِئِذٍ‏.‏
