Arabic hadith text
وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَيْسَ شَيْءٌ أَكْرَمَ عَلَى اللَّهِ مِنَ الدُّعَاءِ»
Translation

Abu Huraira reported God’s messenger as saying, “Nothing is more honourable in God’s sight than supplication.” Tirmidhi and Ibn Majah transmitted it, Tirmidhi saying this is a hasan gharib tradition.
