Arabic (Original)
أَخْبَرَنَا أَبُو خَلِيفَةَ قَالَ حَدَّثَنَا الْقَعْنَبِيُّ قَالَ حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ مُحَمَّدٍ عَنْ شَرِيكِ بْنِ أَبِي نَمِرٍ أَنَّهُ سَمِعَ أَنَسَ بْنَ مَالِكٍ يَقُولُ «مَا صَلَّيْتُ وَرَاءَ أَحَدٍ قَطُّ أَخَفَّ صَلَاةً مِنْ صَلَاةِ رَسُولِ اللَّهِ ﷺ وَلَا أَتَمَّ وَإِنْ كَانَ رَسُولُ اللَّهِ ﷺ يَسْمَعُ بُكَاءَ الصَّبِيِّ وَرَاءَهُ فَيُخَفِّفُ مَخَافَةَ أَنْ تُفْتَنَ أُمُّهُ»
English Translation
Anas ibn Malik said: 'I have never prayed behind anyone whose prayer was lighter than the prayer of the Messenger of Allah (peace and blessings of Allah be upon him), nor more complete. If the Messenger of Allah (peace and blessings of Allah be upon him) heard the crying of a child behind him, he would lighten the prayer for fear that the child's mother would be tried.'
