Yahya related to me from Malik from Ayyub ibn Habib, the mawla of
Sad ibn Abi Waqqas that Abu'l-Muthanna al-Juhani said, "I was with
Marwan ibn al-Hakam and Abu Said al-Khudri came to him. Marwan ibn al-
Hakam said to him, 'Have you heard that the Messenger of Allah, may
Allah bless him and grant him peace, forbade blowing into drinks?' Abu
Said said to him, 'Yes.' A man said to him, 'Messenger of Allah, I am
not quenched from one breath.' The Messenger of Allah, may Allah bless
him and grant him peace, said to him, 'Remove the cup from your mouth
and then breathe.' He said, 'Sometimes I see something floating in
it?' He said, 'Then pour it out.'"
Muwatta Malik Book 49, Hadith 12
That the Messenger of Allah (ﷺ) said: "Wearing silk and gold has made unlawful for the males of my Ummah and lawful for its females.
There are narrations on this topic from 'Umar, 'Ali, 'Uqbah bin 'Amir, Anas, Umm Hani, Hudhaifah, 'Abdullah bin 'Amr, 'Imran bin Husain, 'Abdullah bin Az-Zubair, Jabir, Abu Raihanah, Ibn 'Umar, Al-Bara', and Wathilah bin Al-Asqa', and this Hadith is Hasan Sahih.
Jami` at-Tirmidhi Book 24, Hadith 1
from Al-Bara (regarding): And do not aim at that which is bad to spend from it (2:267) - he said: "It was revealed about us, the people of the Ansar who were date-palm owners. A man would bring the amount of dates that he would from his date-palms, either a lot or a little. A man would bring a cluster or two and hang it in the Masjid. The people of As-Suffah did not have food, so one of them would go up to the cluster and hit it with his stick, and unripe and ripe dates would fall, and he would eat. Some people did not hope for good, so a man would bring a cluster with pitless and hard dates, and a cluster with damaged dates, and hang it. So Allah, Blessed and Most High, revealed: O you who believe! Spend of the good things which you have earned, and of that which We have produced from the earth for you, and do not aim at that which is bad to spend from it (2:267). They said: 'If one of you were given similar to what he gave, he would take it except bashfully with your eyes closed.' So after that, one of us would bring the best that we had."
