An-Nu'mān ibn Bashīr (may Allah be pleased with him) reported: I heard the Messenger of Allah (may Allah's peace and blessings be upon him) say, as An-Nu'mān dropped his two fingers to his ears: "Verily, the lawful is clear, and the unlawful is clear, and between them are doubtful matters many people do not know. Whoever avoids doubtful matters clears his liability regarding his religion and his honor, and whoever falls into doubtful matters will fall into the unlawful, just like the shepherd who grazes his animals in the vicinity of a prohibited pasture and is thus likely to graze therein. Verily, every king has a protected area, and the protected area of Allah is His prohibitions. Verily, in the body, there is a piece of flesh; if it is sound, the entire body will be sound, and if it is corrupt, the entire body will be corrupt; verily, that is the heart."

Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported: The Prophet (may Allah's peace and blessings be upon him) said: "Do not revile my Companions, for if anyone of you spends gold equal to Mount ’Uhud (in Allah's cause), it will not be equal to a Mudd or even half a Mudd spent by one of them."

Ibn ‘Abbās (may Allah be pleased with him) reported: One day, I was riding behind the Prophet (peace and blessings of Allah be upon him), and he said: "O boy, I shall teach you some words: Be mindful of Allah, and Allah will protect you. Be mindful of Allah, and you will find Him before you. If you ask, ask Allah; if you seek help, seek help from Allah. And know that if the Ummah were to gather together to benefit you with anything, they would not benefit you except with what Allah had already prescribed for you. And if they were to gather together to harm you with anything, they would not harm you except with what Allah had already prescribed against you. The pens have been lifted, and the scrolls have dried."

Sufyān ibn ‘Abdullah ath-Thaqafi (may Allah be pleased with him) reported: I said: O Messenger of Allah, tell me something about Islam regarding which I can ask none but you. He (may Allah's peace and blessings be upon him) said: "Say: I believe in Allah, then remain steadfast."

An-Nu‘mān ibn Bashīr (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "The believers, in their mutual love, compassion, and sympathy, are like a single body; if one of its organs suffers, the whole body will respond with sleeplessness and fever."

‘Uthmān ibn ‘Affān (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "Whoever performs ablution perfectly, his sins will come out from his body, to the extent that it will come out from under his nails."

Abu Hurayrah (may Allah be pleased with him) reported: A man asked the Messenger of Allah (may Allah's peace and blessings be upon him), saying: O Messenger of Allah, we travel by sea, and we carry with us a little water. If we make ablution with it, we will be thirsty. Can we make an ablution with the seawater? The Messenger of Allah (may Allah's peace and blessings be upon him) said: "Its water is purifying, and its dead animals are lawful."

‘Abdullah ibn ‘Umar (may Allah be pleased with him and his father) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) was asked about water that is frequented by animals and beasts of prey, and he (may Allah's peace and blessings be upon him) said: "If the water is two pitchers, it will bear no impurity."

Abu Ayyūb al-Ansāri (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "When you go to a place to relieve yourselves, do not face or turn your back to the Qiblah (prayer direction); rather, turn towards the east or the west." Abu Ayyūb said: We came to the Levant and found lavatories built in the direction of the Qiblah, so, we used to divert ourselves and ask forgiveness from Allah Almighty.

Abu Qatādah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "None of you should hold his penis with his right hand while urinating, nor wipe himself after answering the call of nature using his right hand, nor breathe into the vessel."

Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "If any of you wakes up from his sleep, let him blow water out of his nose three times, as the devil spends the night on his nostrils."

Anas (may Allah be pleased with him) reported: The Prophet (may Allah's peace and blessings be upon him) used to take a ritual bath with one Sā‘ up to five Mudds, and he used to perform ablution with one Mudd.
