Peacemaking

Volume 3, Book 49, Number 855:
Narrated Sahl bin Sad:
There was a dispute amongst the people of the tribe of Bani 'Amr bin 'Auf. The Prophet went to them along with some of his companions in order to make peace between them. The time for the prayer became due but the Prophet did not turn up; Bilal pronounced the Adhan (i.e. call) for the prayer but the Prophet did not turn up, so Bilal went to Abu Bakr and said, "The time for the prayer is due and the Prophet i detained, would you lead the people in the prayer?" Abu Bakr replied, "Yes, you wish." So, Bilal pronounced the Iqama of the prayer and Abu Bakr went ahead (to lead the prayer), but the Prophet came walking among the rows till he joined the first row. The people started clapping and they clapped too much, and Abu Bakr used not to look hither and thither in the prayer, but he turned round and saw the Prophet standing behind him. The Prophet beckoned him with his hand to keep on praying where he was. Abu Bakr raised his hand and praised Allah and then retreated till he came in the (first) row, and the Prophet went ahead and lead the people in the prayer. When the Prophet finished the prayer, he turned towards the people and said, "O people! When something happens to you during the prayer, you start clapping. Really clapping is (permissible) for women only. If something happens to one of you in his prayer, he should say: 'Subhan Allah', (Glorified be Allah), for whoever hears him (saying so) will direct his attention towards him. O Abu Bakr! What prevented you from leading the people in the prayer when I beckoned to you (to continue)?" Abu Bakr replied, "It did not befit the son of Abu Quhafa to lead the prayer in front of the Prophet.

Narrated Anas:
It was said to the Prophet "Would that you see Abdullah bin Ubai." So, the Prophet went to him, riding a donkey, and the Muslims accompanied him, walking on salty barren land. When the Prophet reached 'Abdullah bin Ubai, the latter said, "Keep away from me! By Allah, the bad smell of your donkey has harmed me." On that an Ansari man said (to 'Abdullah), "By Allah! The smell of the donkey of Allah's Apostle is better than your smell." On that a man from 'Abdullah's tribe got angry for 'Abdullah's sake, and the two men abused each other which caused the friends of the two men to get angry, and the two groups started fighting with sticks, shoes and hands. We were informed that the following Divine Verse was revealed (in this concern):-- "And if two groups of Believers fall to fighting then, make peace between them." (49.9)

Narrated Abu Huraira and Zaid bin Khalid Al-Juhani:
A bedouin came and said, "O Allah's Apostle! Judge between us according to Allah's Laws." His opponent got up and said, "He is right. Judge between us according to Allah's Laws." The bedouin said, "My son was a laborer working for this man, and he committed illegal sexual intercourse with his wife. The people told me that my son should be stoned to death; so, in lieu of that, I paid a ransom of one hundred sheep and a slave girl to save my son. Then I asked the learned scholars who said, "Your son has to be lashed one-hundred lashes and has to be exiled for one year." The Prophet said, "No doubt I will judge between you according to Allah's Laws. The slave-girl and the sheep are to go back to you, and your son will get a hundred lashes and one year exile." He then addressed somebody, "O Unais! go to the wife of this (man) and stone her to death" So, Unais went and stoned her to death.
