Hadith 7:10
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.
وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَيْسَ شَيْءٌ أَكْرَمَ عَلَى اللَّهِ مِنَ الدُّعَاءِ»
