Hadith on Salat: The Prophet prays lightly, yet perfectly

Anas ibn Malik reported: I never prayed behind an Imam who prayed so lightly, yet so perfectly as the Prophet, peace and blessings be upon him. He would hear a child crying and lighten the prayer, fearing it would put his mother to trial.

عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ مَا صَلَّيْتُ وَرَاءَ إِمَامٍ قَطُّ أَخَفَّ صَلَاةً وَلَا أَتَمَّ مِنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَإِنْ كَانَ لَيَسْمَعُ بُكَاءَ الصَّبِيِّ فَيُخَفِّفُ مَخَافَةَ أَنْ تُفْتَنَ أُمُّهُ
