Muhammad ibn Maslamah
Ibn Maslamah witnessed all the battles except for the expedition of Tabuk, as he was appointed as deputy governor of Medina during the campaign.
[8]: 330 [6]: 347 Later, when the Muslims defeated the Qaynuqa tribe in April, Ibn Maslamah supervised their expulsion from Medina and the seizure of their possessions.
[9]: 89 In the same year, approximately in the month of September, Ibn Maslama was sent by Muhammad along with some of his kinsmen and allied tribe of Aws on a mission to assassinate Ka'b ibn al-Ashraf, a Jewish man who would recite defamatory poetry about Muhammad and also made explicit poems about Muslim women.
Ibn Maslamah was put in charge of fifty men that were tasked with patrolling the camp at night time before the battle.
[1]: 347 Later, In August 625 Ibn Maslamah brought the message to the Jewish tribe of Banu Nadir that Muhammad wanted to expel them.
[9]: 179–180 [12]: 158 Later, when the Nadir tribe surrendered to Muhammad and were expelled from Medina, it was Ibn Maslamah who supervised their exit and collected all their confiscated property and weapons.
[9]: 183, 185 In the next year, 626, in between August and September, Ibn Maslamah was involved with the cattle-raid on Invasion of Dumatul Jandal, where he was the only Muslim who captured a human prisoner; the other raiders only brought cattle and camels.
The conversion of Thumamah had significant political impact on Muslim Medina for two reasons: The next major battle Ibn Maslamah participated in was the Battle of the Trench which occurred in the spring of 627, when the coalitions of Quraysh, Ghatafan, and other smaller tribes numbered to 10,000, besieged Medina.
Ibn Maslamah told Muhammad that he had deliberately allowed 'Amr to escape because he had not participated in the treachery of the Qurayza.
[5]: 463 [9]: 247–248 [17]: 32 When the Qurayza prisoners were being sold, Ibn Maslamah bought a woman and her two sons for 45 coins of dinar.
Ibn Maslamah fell with a wounded ankle although he managed to survive and escape, as the enemies stripped the corpses and departed.
Later, a Muslim happened to pass the site, and on finding Ibn Maslamah alive, he gave him food and water and transported him back to Medina.
[9]: 203 During the Pledge of the Tree, Ibn Maslamah was among the twenty horsemen who were sent as an advance guard to Hudaybiyyah[9]: 286 and he was on the night-watch roster.
[9]: 324 On the same day, Ibn Maslamah avenged his brother by killing Marhab in a vicious duel which was so intense to the point that palm trees within the garden outside the fortress wall, were chopped-off completely.
[5]: 515 [9]: 331 [17]: 123 [19]: 135 After all of eight fortresses in Khaybar were subdued, Ibn Maslamah and the Muslim forces marched again and passed the Jewish tribe of Wadi al-Qura, which they fought on the basis that until either surrendered.
The Muslims stayed for a while dividing the spoils of war, Ibn Maslamah was awarded one share in Wadi al-Qura.
[1]: 347 [9]: 488 During the Caliphate Ibn Maslamah worked as a tax-collector, bringing in zakat that was due from the Ashja tribe which was a subtribe of Ghatafan.
Sa'd ibn Abi Waqqas, hero of Battle of al-Qadisiyyah and Siege of Ctesiphon (637), had built a public citadel next door to his own house.
[21] He refused all of Sa'd's offers of hospitality, but handed him a letter from Umar reminding him that the citadel should be available to the public and suggesting that he move his house.
Nearly everyone expressed satisfaction with Saad's conduct as governor; but eventually there was an accusation that he did not lead the prayers correctly and spent too much time hunting.
When Uthman warned from the pulpit that the Egyptian rebels had been cursed by Muhammad, Ibn Maslamah stood up and testified he also heard from Muhammad himself regarding the Hadith which was being narrated by Uthman at the pulpit, that those dissidents who were prophesied before, will cause trouble, which the chroniclers thought particularly during this time .
"[23]: 191, 194 Ibn Maslamah then returned to the private chamber of the Caliph and warned him to escape with his life, as he thought the dissidents will kill Uthman.
[23]: 191–192, 197 The Egyptians approached Ibn Maslamah directly to advise him of the discovery of a letter in which Uthman had ordered various officials to be flogged.
Uthman denied all knowledge of the letter; Ibn Maslamah and Ali believed him and decided that it must have been forged by Marwan.
The Egyptians countered that if he was so incompetent that it was possible for someone to forge letters by appropriating his personal scribe, seal, slave and camel, then he ought to abdicate anyway.
Suhayb ar-Rumi managed to calm down the immediate situation, but the reports of half-hearted support for Ali returned both to him and to his opponents.
Ibn Maslamah replied that he had left Medina because he want to avoid the civil war within the caliphate.
[1]: 349 When Abu Bakr raised the legal question of the inheritance due to a grandmother, Ibn Maslamah testified that Muhammad had allocated her one-sixth of the estate.
