The supplication that he (the Prophet made very frequently is this:" O Allah, grant us the good in this world and the good in the Hereafter and save us from the torment of Hell-Fire." He (Qatada) said that whenever Anas had to supplicate he made this very supplication, and whenever he (intended) to make another supplication he (inserted) this very supplication in that.  

سَأَلَ قَتَادَةُ أَنَسًا أَىُّ دَعْوَةٍ كَانَ يَدْعُو بِهَا النَّبِيُّ ﷺ أَكْثَرَ قَالَ كَانَ أَكْثَرُ دَعْوَةٍ يَدْعُو بِهَا يَقُولُ اللَّهُمَّ آتِنَا فِي الدُّنْيَا حَسَنَةً وَفِي الآخِرَةِ حَسَنَةً وَقِنَا عَذَابَ النَّارِ قَالَ وَكَانَ أَنَسٌ إِذَا أَرَادَ أَنْ يَدْعُوَ بِدَعْوَةٍ دَعَا بِهَا فَإِذَا أَرَادَ أَنْ يَدْعُوَ بِدُعَاءٍ دَعَا بِهَا فِيهِ  

Which Supplication would the Prophet ﷺ often make ? He replied: The supplication he would usually recite was: "O Allah, give us in this world what is good and in the next what is good, and protect us from the punishment of Hell-fire". The version of Ziyad adds: When Anas wished to supplicate, he uttered this supplication. When he uttered some other supplication, he combined it with this supplication.  

سَأَلَ قَتَادَةُ أَنَسًا أَىُّ دَعْوَةٍ كَانَ يَدْعُو بِهَا رَسُولُ اللَّهِ ﷺ أَكْثَرَ قَالَ كَانَ أَكْثَرُ دَعْوَةٍ يَدْعُو بِهَا اللَّهُمَّ رَبَّنَا آتِنَا فِي الدُّنْيَا حَسَنَةً وَفِي الآخِرَةِ حَسَنَةً وَقِنَا عَذَابَ النَّارِ وَزَادَ زِيَادٌ وَكَانَ أَنَسٌ إِذَا أَرَادَ أَنْ يَدْعُوَ بِدَعْوَةٍ دَعَا بِهَا وَإِذَا أَرَادَ أَنْ يَدْعُوَ بِدُعَاءٍ دَعَا بِهَا فِيهَا

(Using translation from Abū Dāʾūd 1519)  

سَأَلَ قَتَادَةُ أَنَسًا أَيُّ دَعْوَةٍ كَانَ أَكْثَرَ يَدْعُو بِهَا النَّبِيُّ ﷺ؟ قَالَكَانَ أَكْثَرُ دَعْوَةٍ يَدْعُو بِهَا رَسُولُ اللهِ ﷺ اللهُمَّ رَبَّنَا آتِنَا فِي الدُّنْيَا حَسَنَةً وَفِي الْآخِرَةِ حَسَنَةً وَقِنَا عَذَابَ النَّارِ وَكَانَ أَنَسٌ إِذَا أَرَادَ أَنْ يَدْعُوَ بِدَعْوَةٍ دَعَا بِهَا وَإِذَا أَرَادَ أَنْ يَدْعُوَ بِدُعَاءٍ دَعَا بِهَا فِيهِ
