(65) باب مَنْ أَخَفَّ الصَّلاَةَ عِنْدَ بُكَاءِ الصَّبِيِّ
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.
