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

Jabir reported God’s messenger as saying, “No one offers a supplication without God bringing him what he asks or keeping away from him a like amount of evil, provided he does not ask for something sinful or for breaking ties of relationship.” Tirmidhi transmitted it.
