Narrated Abu Hurairah (RA):

The Prophet (ﷺ) said: "If you hear the Iqamah, you must walk to the prayer (place) with tranquility and dignity, and do not hasten; and whatever portion of the prayer you get (along with the Imam) offer it, and complete afterwards whatever you missed. [Agreed upon, and the wording is al-Bukhari's).

وَعَنْ أَبِي هُرَيْرَةَ ‏- رضى الله عنه ‏- عَنْ اَلنَّبِيِّ ‏- صلى الله عليه وسلم ‏-قَالَ: { إِذَا سَمِعْتُمْ اَلْإِقَامَةَ فَامْشُوا إِلَى اَلصَّلَاةِ, وَعَلَيْكُمْ اَلسَّكِينَةُ وَالْوَقَارُ, وَلَا تُسْرِعُوا, فَمَا أَدْرَكْتُمْ فَصَلُّوا, وَمَا فَاتَكُمْ فَأَتِمُّوا } مُتَّفَقٌ عَلَيْهِ, وَاللَّفْظُ لِلْبُخَارِيِّ .‏ [1]‏ .‏
