Ibn Sa’d narrated that the Messenger of Allah (PBUH) said: .

"Amir kaum itu ialah Zayd bin Harithah; jika dia terbunuh, maka amirnya ialah Ja'far bin Abi Talib; dan jika dia terbunuh, amirnya ialah Abdullah bin Ruwahah; dan jika dia terbunuh, biarlah kaum Muslimin memilih seorang lelaki daripada kalangan mereka dan menjadikannya amir mereka."

“The amir of the people is Zayd ibn Haritha; if he was killed then the amir is Ja’far ibn Abi Talib; and if he was killed the amir is Abdullah ibn Ruwahah; and if he was killed let the Muslims choose one man from among them and make him their amir.”.

Al-Bukhari meriwayatkan bahawa Abdullah ibn ‘Umar (ra) berkata:

Al-Bukhari narrated that Abdullah ibn ‘Umar (ra) said: .

Rasulullah ﷺ melantik Zayd bin Haritha sebagai amir dalam ekspedisi Mu'tah…

"Nabi (PBUH) menghantar satu tentera dan melantik Usamah bin Zayd sebagai amir ke atas mereka. Sebahagian orang mencela kepimpinannya, maka Nabi ﷺ bersabda: 'Jika kamu mencela kepimpinannya, sesungguhnya kamu telah mencela kepimpinan ayahnya sebelum ini. Demi Allah! Dia layak memegang kepimpinan...'" [Bukhari, Sahih, #4250 dan Muslim, Sahih, #2436]. Para Sahabat biasa menamakan tentera Mu'tah sebagai tentera amir-amir. Muslim meriwayatkan daripada Ibn Buraydah, katanya: "Rasulullah ﷺ biasa memberi nasihat kepadanya apabila melantik seorang amir ke atas sebuah tentera atau satu ekspedisi..."

“The Prophet (PBUH) sent an army and appointed Usama ibn Zayd as an amir over them. Some people defamed his leadership, so the Prophet (PBUH) said: ‘If you defame his leadership you defamed the leadership of his father before. By Allah! He is worthy of leadership…’” [Bukhari, Sahih, #4250 and Muslim, Sahih, #2436]. The Sahabah used to call the army of Mu’tah the army of amirs. Muslim narrated from Ibn Buraydah, he said: “The Messenger of Allah ( PBUH) used to advise him when appointing an amir over an army or an expedition…” .
