An-Nu'man b. Bashir told that his father brought him to God’s Messenger and said, "I have given this son of mine a slave.”He asked whether he had given all his children the same, and when he replied that he had not, he told him to take him back. A version reports him as asking, "Would you like them to show you equal filial piety?”When he replied that he would, he said, "Don’t do it then.”In a version he said that his father gave him a gift, but' Amra* daughter of Rawaha said, "I shall not be satisfied till you call God's Messenger as witness.”So he went to him and said, "I have given my son from ‘Amra daughter of Rawaha a gift and she has ordered me to call you as witness, Messenger of God.”He asked whether he had given the rest of his children the same, and when he replied that he had not, he said, "Fear God and act equally with your children.”He said that he then returned and took back his gift. A version quotes him as saying, "I shall not be a witness to oppression.”* She was the wife of Bashir b, Sad al-Ansari and mother of an-Nu'man (Isti'ab, p. 746). (Bukhari and Muslim.)

Abu Dawud, Tirmidhi, Nasa’i and Ibn Majah transmitted it, Tirmidhi saying it is sahih.

Abu Huraira said that a desert Arab presented God’s Messenger with a young she-camel, in return for which he gave him six young she- camels. He was displeased, and when the Prophet heard that, he praised and extolled God and said,“So and so presented me with a she-camel and I gave him six young she-camels in return for it, but he was displeased. I feel inclined to accept a present only from a Qurashi, an Ansari, a Thaqafi, or a Dausi." Tirmidhi, Abu Dawud and Nasa’i transmitted it.

Jabir reported the Prophet as saying,“If anyone is given a gift and has the means he should make a return for it, but if he has not the means he should express commendation, for he who expresses commendation has given thanks, he who conceals a matter has been ungrateful, and he who decks himself with what he has not been given is like him who puts on the two garments of falsehood.”Tirmidhi and Abu Dawud transmitted it.

Anas said that when God’s Messenger came to Medina the Emigrants came to him and said,“Messenger of God, we have never seen people more liberal out of abundance or better in giving help when they have little than a people among whom we have settled. They have removed our trouble and shared with us their pleasant things so that we are afraid they will get the whole reward." He replied, ‘No, as long as you make supplication to God for them and express commendation of them*.”* They have no reason to fear that the Ansar will get all the reward from God so long as due expression of thanks is made. Tirmidhi transmitted it saying that it is sahih.

‘A’isha reported the Prophet as saying, "Give presents to one another, for a present removes grudges.”…transmitted it. (Mirqat, 3:380 says that Tirmidhi is the source in which this tradition is found. I have looked for it with the help of the Concordance, but have been unable to find it.
