Narrated Abu Huraira:

Allah 's Apostle said, "Treat women nicely, for a women is created from a rib, and the most curved portion of the rib is its upper portion, so, if you should try to straighten it, it will break, but if you leave it as it is, it will remain crooked. So treat women nicely."

Volume 3, Book 47, Number 781:
Narrated Ibn 'Umar:

That he was in the company of the Prophet on a journey, riding a troublesome camel belonging to 'Umar. The camel used to go ahead of the Prophet, so Ibn 'Umar's father would say, "O 'Abdullah! No one should go ahead of the Prophet." The Prophet said to him, "Sell it to me." 'Umar said to the Prophet "It is for you." So, he bought it and said, "O 'Abdullah! It is for you, and you can do with it what you like."

Abu Musa Al-Ash`ari (May Allah be pleased with him) reported: The Prophet (PBUH) said, "Read the Qur'an regularly. By the One in Whose Hand Muhammad's soul is, it escapes from memory faster than a camel does from its tying ropes.''
[Al-Bukhari and Muslim].

Abu Sa`id Ar-Rafi` bin Al-Mu`alla (May Allah be pleased with him) reported: The Messenger of Allah (PBUH) said, "Shall I teach you the greatest Surah in the Qur'an before you leave the mosque?'' Then he (PBUH), took me by the hand, and when we were about to step out, I reminded him of his promise to teach me the greatest Surah in the Qur'an. He (PBUH) said, "It is `Alhamdu lillahi Rabbil `Alamin (i.e., Surat Al-Fatihah) which is As-Sab` Al-Mathani (i.e., the seven oft-repeated Ayat) and the Great Qur'an which is given to me.''
[Al-Bukhari].

`Abdullah bin `Abbas (May Allah be pleased with them) reported: Messenger of Allah (PBUH) said that Allah, the Glorious, said: "Verily, Allah (SWT) has ordered that the good and the bad deeds be written down. Then He explained it clearly how (to write): He who intends to do a good deed but he does not do it, then Allah records it for him as a full good deed, but if he carries out his intention, then Allah the Exalted, writes it down for him as from ten to seven hundred folds, and even more. But if he intends to do an evil act and has not done it, then Allah writes it down with Him as a full good deed, but if he intends it and has done it, Allah writes it down as one bad deed".
[Al-Bukhari and Muslim].

Rasullulah (pbuh) said: �Verily, a Surah from the Qur�an consisting of thirty ayat (verses) interceded for a person until he was pardoned (by Allah), and that was Tabarakallathee Biyadihil Mulk (Surah Al-Mulk). (Tirmizi, Haakim)

Abu Hurairah (May Allah be pleased with him) said: The Messenger of Allah (PBUH) said, "By the One in Whose Hand my soul is! If you do not commit sins, Allah would replace you with a people who would commit sins and seek forgiveness from Allah; and Allah will certainly forgive them.''
[Muslim].

Commentary: This Hadith does not mean that Allah likes disobedience. But by this way of description, the aim is to emphasize the importance of seeking forgiveness from Allah. We know that every man commits sins. But Allah likes those people who, after committing a sin, do not stick to it, but right away seek forgiveness for their sins from Allah. They weep and express sorrow before Allah. By seeking forgiveness, a relationship with Allah is established between man and his Creator. So seeking forgiveness is a very good act.

Sahih Bukhari
Volume 7, Book 69, Number 481:

Narrated Ibn 'Umar:

Allah's Apostle said, "Whoever drinks alcoholic drinks in the world and does not repent (before dying), will be deprived of it in the Hereafter."

On the authority of Abu Hurayrah (may Allah be pleased with him), who said that the Messenger of Allah (peace be upon him) said:
When Allah decreed the Creation He pledged Himself by writing in His book which is laid down with Him: My mercy prevails over my wrath.

It was related by Muslim (also by al-Bukhari, an-Nasa'i and Ibn Majah).
