Abu Dawood: Hadith 942

sahl b. Sa'd said; Fighting took place amongst the tribe of Banu "Amr b. "Awf. This (the news) reached the prophet (ﷺ). He came to them for their reconciliation after the noon prayer . he said to Bilal; If the time of the afternoon prayer comes, and I do not return to you, then ask Abu Bakr to lead the people in prayer. When the time of the afternoon prayer came, Bilal called the Adhan and pronounced the Iqamah and then asked Abu Bakr (to lead the prayer). He stepped forward. The narrator reported this tradition to the same effect. In the end he (the prophet) said; if anything happens to you during prayer, the men should say" Glory be to Allah," and the women should clap.
