عَنِ النُّعْمَانِ بْنِ بَشِيرٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «الدُّعَاءُ هُوَ الْعِبَادَةُ» ثُمَّ قَرَأَ: (وَقَالَ رَبُّكُمُ ادْعُونِي أَسْتَجِبْ لَكم) رَوَاهُ أَحْمَدُ وَالتِّرْمِذِيُّ وَأَبُو دَاوُدَ وَالنَّسَائِيُّ وَابْنُ مَاجَه

Ibn Mas'ud reported God’s messenger as saying, “Ask God for some of His bounty, for God likes to be asked, and the most excellent worship is expectation of relief.” Tirmidhi transmitted it, saying this is a gharib tradition.
