Sa'd bin Ibrahim سعد بن إبراهيم بن عبد الرحمن · The Book of Purification and its Sunnah

The Messenger of Allah said: "Performing ablution properly is half of faith, saying Al-Hamdu Lillah fills the Scale (of good deeds), saying Subhan-Allah and Allahu Akbar fills the heavens and the earth, prayer is light, Zakat is proof, patience is brightness and the Qur'an is proof for you or against you. Every person goes out in the morning to sell his soul, so he either frees it or destroys it.'"

He heard Abu Hurairah say: "A man came to the Messenger of Allah and said: "O Messenger of Allah, we travel by sea and carry a small amount of water with us. If we use it for ablution, we will become thirsty. Can we perform ablution with seawater?' The Messenger of Allah said: 'Its water is a means of purification, ad its dead meat is permissible. (i.e. the fish found dead in the sea).'"

The Prophet said: "There is no prayer for one who does not have ablution, and there is no ablution for one who does not mention the Name of Allah (before it). There is no prayer for one who does not send blessing, (Salat) upon the Prophet, and there is no prayer for one who does not love the Ansar." (Da'if) Another chain with similar wording.
