Book 10: Call to Prayers (Adhaan) · Narrated by Anas bin Malik
Arabic
حَدَّثَنَا خَالِدُ بْنُ مَخْلَدٍ، قَالَ حَدَّثَنَا سُلَيْمَانُ بْنُ بِلاَلٍ، قَالَ حَدَّثَنَا شَرِيكُ بْنُ عَبْدِ اللَّهِ، قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ، يَقُولُ مَا صَلَّيْتُ وَرَاءَ إِمَامٍ قَطُّ أَخَفَّ صَلاَةً وَلاَ أَتَمَّ مِنَ النَّبِيِّ صلى الله عليه وسلم، وَإِنْ كَانَ لَيَسْمَعُ بُكَاءَ الصَّبِيِّ فَيُخَفِّفُ مَخَافَةَ أَنْ تُفْتَنَ أُمُّهُ.
English translation
Narrated Anas bin Malik:I never prayed behind any Imam a prayer lighter and more perfect than that behind the Prophet (ﷺ) and he used to cut short the prayer whenever he heard the cries of a child lest he should put the child's mother to trial
