The Messenger of Allah ﷺ would listen to the crying of a lad in the company of his mother, in prayer, and he would recite a short surah or a small surah. (Using translation from Muslim 470a)   

كَانَ رَسُولُ اللهِ ﷺ يَسْمَعُ بُكَاءَ الصَّبِيِّ مَعَ أُمِّهِ وَهُوَ فِي الصَّلَاةِ فَيَقْرَأُ بِالسُّورَةِ الْخَفِيفَةِ أَوْ بِالسُّورَةِ الْقَصِيرَةِ  

The Prophet ﷺ said, "When I start the prayer I intend to prolong it, but on hearing the cries of a child, I cut short the prayer because I know that the cries of the child will incite its mother's passions." (Using translation from Bukhārī 709)   

أَنَّ النَّبِيَّ ﷺ قَالَ إِنِّي لَأَدْخُلُ فِي الصَّلَاةِ وَأَنَا أُرِيدُ أَنْ أُطِيلَهَا فَأَسْمَعُ بُكَاءَ الصَّبِيِّ فَأَتَجَوَّزُ فِي صَلَاتِي مِمَّا أَعْلَمُ مِنْ شِدَّةِ وَجْدِ أُمِّهِ مِنْ بُكَائِهِ  

[Machine] The Messenger of Allah ﷺ said, "Verily, I enter the prayer intending to prolong it, but when I hear the crying of a baby, I shorten it out of knowing the distress of its mother because of it."  

قَالَ رَسُولُ اللهِ ﷺ إِنِّي لَأَدْخُلُ الصَّلَاةَ أُرِيدُ إِطَالَتَهَا فَأَسْمَعُ بُكَاءَ الصَّبِيِّ فَأُخَفِّفُ مِمَّا أَعْلَمُ مِنْ شِدَّةِ وَجْدِ أُمِّهِ بِهِ
