عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((أَتُحِبُّونَ أَنْ تَجْتَهِدُوا فِي الدُّعَاءِ؟ قُولُوا اللَّهُمَّ أَعِنَّا عَلَى شُكْرِكَ وَذِكْرِكَ وَحُسْنِ عِبَادَتِكَ))
It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Do you wish to supplicate with full effort? Then say like this: "Allahumma a'inna 'ala shukrika wa dhikrika wa husni 'ibadatika." (O Allah! Help us to thank You, remember You, and worship You in the best manner.)
