Imaam Tabraani (rahimahullah) replied by reciting the following:

اَللَّهُمَّ لَكَ الْحَمْدُ بِعَدَدِ مَنْ حَمِدَكَ وَلَكَ الْحَمْدُ بِعَدَدِ مَنْ لَمْ يَحْمَدْكَ وَلَكَ الْحَمْدُ كَمَا تُحِبُّ أَنْ تُحْمَدَ اَللَّهُمَّ صَلِّ عَلَى مُحَمَّدٍ بِعَدَدِ مَنْ صَلَّى عَلَيْهِ وَصَلِّ عَلَى مُحَمَّدٍ بِعَدَدِ مَنْ لَمْ يُصَلِّ عَلَيْهِ وَصَلِّ عَلَى مُحَمَّدٍ كَمَا تُحِبُّ أَنْ يُصَلَّى عَلَيْهِ

“O Allah! All praise is due to You alone, equal to the number of all those who praise You, and all praise is due to You alone, equal to the number of all those who do not praise You, and all praise is due to You alone, as You like to be praised. O Allah! Send salutations upon Muhammed (sallallahu ‘alaihi wasallam) equal to the number of all those who send salutations upon him, and send salutations upon him equal to all those who do not send salutations upon him, and send salutations upon him as you like salutations to be sent upon him.”

On hearing the unique praise of Allah Ta‘ala and durood that Imaam Tabraani (rahimahullah) had recited, Rasulullah (sallallahu ‘alaihi wasallam) smiled, until his blessed front teeth could be seen and the noor (divine radiance) that would emit from the gap between his blessed front teeth was apparent.
