What I have preserved about the campaign against Banu al-Mustaliq

Ibn Awn says: I wrote to Nafi' asking him about inviting the polytheists (to Islam), and he wrote to me: Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) informed me that the Prophet (peace and blessings be upon him) attacked Banu al-Mustaliq while they were unaware and their animals had come to the water. Sayyidah Juwayriyah bint al-Harith (may Allah be pleased with her) was among those who fell to him as captives, and I was among the horsemen.

Ibn Muhayriz says: Abu Sirmah al-Mazini and I went to Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) and asked him about coitus interruptus ('azl). He replied: We took noble daughters of the Arabs captive. We captured the women of Banu al-Mustaliq, and we intended to practice 'azl (with them), and we were eager to receive ransom. Some of us said: "The Messenger of Allah (peace and blessings be upon him) is present among you, and you practice 'azl?" So we came to him (peace and blessings be upon him) and said: "O Messenger of Allah (peace and blessings be upon him), we have taken noble daughters of the Arabs captive. We have made the women of Banu al-Mustaliq captives. We intend to practice 'azl, and we are eager to receive ransom." The Prophet (peace and blessings be upon him) said: "There is no harm upon you if you do not do it, for any soul that Allah Almighty has written is to exist until the Day of Resurrection will certainly come into being."

Hisham narrates from his father that when the Companions of the Prophet (peace and blessings be upon him) reached the halting place during the expedition of Banu al-Mustaliq, whose people had gone, driven away by them, with chickens left behind in the place, a quarrel broke out between the young boys of the Muhajirun and the Ansar. The boys of the Muhajirun called out: "Ya lal-Muhajirin (O Muhajirun, to our aid)!" and the boys of the Ansar called out: "Ya lal-Ansar (O Ansar, to our aid)!" This news reached Abdullah bin Ubayy bin Salul, and he said: "Indeed, by Allah, if the Ansar did not spend on the Muhajirun, they would leave from around him (peace and blessings be upon him). Indeed, by Allah, if we return to Madinah, the honorable will most certainly expel the abased from it." This reached the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) ordered the Companions to march, as though he (peace and blessings be upon him) was keeping them occupied. Then during the journey he (peace and blessings be upon him) found a mounted party of Banu Abd al-Ashhal, and he (peace and blessings be upon him) said to them: "Do you not know what the hypocrite Abdullah bin Ubayy has said?" They asked: "O Messenger of Allah (peace and blessings be upon him), what has he said?" He (peace and blessings be upon him) said: "He has said: 'Indeed, by Allah, if you (Ansar) do not spend on them (the Muhajirun), they will leave Muhammad (peace and blessings be upon him). Indeed, by Allah, if we return to Madinah, the honorable will most certainly expel the abased from it.'" They said: "O Messenger of Allah, he spoke the truth. By Allah, you are the honorable one and he is the abased."
