Hadith 335

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).
