The Messenger of Allah said: "None of you should fail to say, when he enters his toilet: 'Allahumma inni a`udhu bika minar-rijsin-najis, al-khabithil-mukhbith, ash-Shaitanir-rajim (O Allah, I seek refuge with You from the filthy and impure, the evil one with evil companions, the accursed Shaitan).'" (Da'if)Another chain with a slightly different wording from Ibn Abi Maryam who mentioned similar, but he did not say in his narration: "Minar-rijsin-najis (From the filthy and the impure)" he only said: "Minal-khabithil-mukhbith, ash-Shaitanir-rajim (From the evil one with evil companions, the accursed Shaitan)."

The Messenger of Allah came to the garbage dump of some people and he urinated on it standing up.

"The Messenger of Allah said: 'Allah does not accept any Salat (prayer) without purification, and He does not accept any charity from Ghulul.'"

The Messenger of Allah said: "Whoever performs ablution and rinses his mouth and nose, his sins will exit through his mouth and nose. When he washes his face, his sins will exit from his face, even from beneath his eyelids. When he washes his hands, his sins will exit from his hands. When he wipes his head, his sins will exit from his head, and even from his ears. When he washes his feet, his sins will exit from his feet, even from beneath his toenails. Then his prayer and walking towards the mosque will earn extra merit for him."

"I saw 'Uthman bin 'Affan sitting in Maqa'id. He called for water and he performed ablution, the he said: 'I saw the Messenger of Allah sitting in this place where I am sitting, performing ablution as I have done. Then he said: "Whoever performs ablution as I have done, his previous sins will be forgiven." And the Messenger of Allah said: "And do not be conceited (due to this great virtue)." (Sahih)Another chain with similar wording.

"The Messenger of Allah said: 'Were it not that it would be too difficult for my Ummah (nation), I would have commanded them to use the tooth stick at every time of prayer.'"

The Messenger of Allah said: "Use the tooth stick, for the tooth stick purifies the mouth and is pleasing to the Lord. Jibril never came to me but he advised me to use the tooth stick, until I feared that it would be made obligatory for me and my Ummah. Were it not that I fear that it would be too difficult for my Ummah, I would have enjoined it upon them. And I use the tooth stick until I fear that I may make the front of my mouth sore.' (i.e. my gums) (or cause my teeth to fall out due to brushing them so often)."

"Whenever the Messenger of Allah entered the toilet, he would say: 'A'udhu Billahi minal-khubthi wa'l-khaba'ith (I seek refuge with Allah from male and female devils).'"

The Messenger of Allah came to the garbage dump of some people and urinated while standing up. (Hasan)Shu'bah said: "That day, 'Asim said: 'Amash reported this from Abu Wa'il, from Hudhaifah, but he did not remember it (correctly). So I asked Mansur about it, and he narrated it to me from Abu Wa'il, from Hudhaifah, that the Prophet came to a dump of some people and urinated while standing.'"

"The Messenger of Allah saw me urinating while standing, and he said: 'O 'Umar, do not urinate standing up.' So I never urinated whilst standing after that."

Another chain with similar wording.

The Messenger of Allah used to perform ablution with a Mudd (of water) and bath with a Sa'.

"The Messenger of Allah said: 'A Mudd is sufficient for the ablution and a Sa' is sufficient for the bath.' A man said: 'It is not sufficient for us.'" He (the narrator) said: "It was sufficient for one who is better than you and had more hair" meaning the Prophet.

"The Messenger of Allah said: 'Allah does not accept any prayer without purification and He does not accept any charity from Ghulul.'" (Sahih)Another chain with similar wording.

"The Messenger of Allah said: 'Allah does not accept any prayer without purification, and He does not accept any charity from ghulul.'"

"I heard the Messenger of Allah say: 'Allah does not accept any prayer without purification, and He does not accept any charity from Ghulul.'"

"The Messenger of Allah said: 'Adhere to righteousness even though you will not be able to do all acts of virtue. Know that among the best of your deeds is prayer and that no one maintains his ablution except a believer.'"

"The Messenger of Allah said: 'When a person performs ablution and washes his hands, his sins exit through his hands. When he washes his face, his sins exit through his face. When he washes his forearms and wipes his head, his sins exit though his forearms and head. When he washes his feet, his sins exit through his feet.'"

"It was said: 'O Messenger of Allah, how will you recognize those whom you have not seen of your Ummah?' He said: 'From the blazes of their foreheads and feet, like horses with black and white traces (which make them distinct from others) which are the traces of ablution.'" (Hasan)Another chain with similar wording.

"Whenever the Messenger of Allah got up for prayer at night to pray Tahajjud (night optional prayer), he would clean his mouth with the tooth stick."
