The Prophet ﷺ said, "Nothing is more honorable to Allah, the Exalted, than supplication."
حدثنا محمد بن يحيى حدثنا أبو داود حدثنا عمران القطان عن قتادة عن سعيد بن أبي الحسن
عن النبي ﷺ قال ليس شيء أكرم على الله سبحانه من الدعاء
Its isnad is daif. It was narrated by Tirmidhi, Supplications, chapter on what has been mentioned regarding the merit of supplication, no. 3370, from the hadith of Abu Dawud Tayalisi, and it is in his Musnad, no. 2582. Tirmidhi said, hasan gharib. Ibn Hibban graded it sahih, no. 2397, as did Hakim, 1/490, and Dhahabi. Its defect is the anaan of Qatada, mentioned previously, no. 175.
