Riyad as-Salihin

The Prophet (ﷺ) gave respite for three days to the family of Ja'far (after his martydom). Then he came and said, "Don't weep for my brother after this day." He said, "Bring all of my nephews to me." We were accordingly brought as if we were chickens. Then he said, "Call for me a barber." He directed him to shave our heads which he did..

The Messenger of Allah (ﷺ) prohibited a woman from shaving her head..

A woman came to the Prophet (ﷺ) and said: "O Messenger of Allah! I have a daughter who had an attack of small pox and her hair fell off. Now I want to celebrate her marriage. Can I get her a wig?" Thereupon the Prophet (ﷺ) said, "Allah has cursed the maker and wearer of a wig.".

A similar narration was narrated on the authority of 'Aishah.

I saw Mu'awiyah (May Allah be pleased with him) during the Hajj (pilgrimage) standing on the pulpit. He took from the guard a bunch of hair, and said: "O people of Al-Madinah! Where are your scholars? (Why do they do not prohibit you) I heard the Prophet (ﷺ) prohibiting from using this (false hair) and saying, 'The people of Bani Israel were ruined when their women wore such hair."'

The Messenger of Allah (ﷺ) cursed the maker and wearer of a wig and the tattooer and the one who is tattooed..

Allah has cursed those women who practise tattooing and those women who have themselves tattooed, and those women who get their hair removed from their eyebrows and faces (except the beard and the mustache), and those who make artificial spaces between their teeth for beauty, whereby they change Allah's creation. A woman started to argue with him, saying: "What is all this?" He replied: "Why should I not curse those whom the Messenger of Allah (ﷺ) cursed and who are cursed in Allah's Book? Allah, the Exalted, has said in His Book:"And whatsoever the Messenger (Muhammad (ﷺ)) gives you, take it; and whatsoever he forbids you, abstain (from it)." (59:7).

The Messenger of Allah (ﷺ) said, "He who does something contrary to our way (i.e., Islam) will have it rejected.".

The Prophet (ﷺ) said, "Do not touch your private parts with your right hand while urinating, nor for washing or cleaning (your private parts); and do not breathe into the drinking vessel from which you drink.".

The Messenger of Allah (ﷺ) said, "None of you should walk wearing one shoe; you should either wear them both or take them off both.".

I heard the Messenger of Allah (ﷺ) saying, "When the lace of one of the shoes of any one of you is cut off, he should not walk with the other until he has got the lace repaired.".

The Messenger of Allah (ﷺ) forbade a person wearing (tying up) his shoe while standing..

The Prophet (ﷺ) said, "Do not keep the fire burning in your homes when you go to bed.".

A house in Al-Madinah was burnt with its occupants inside it one night. When this was reported to the Messenger of Allah (ﷺ) he said, "Fire is your enemy. So, put it out before going to bed.".

The Messenger of Allah (ﷺ) said, "Cover up the (kitchen) containers (i.e., pots, pans, etc.), tie up the mouth of the water-skin, lock up the doors and extinguish the lamps, because Satan can neither untie the water-skin nor open the door nor uncover the containers. If one can cover the cooking pot even by placing a piece of wood across it, and pronounce the Name of Allah on it, let him do it. A mouse can sometimes cause a house to burn along its dwellers."

We have been forbidden to go into excess..

We visited 'Abdullah bin Mas'ud (May Allah be pleased with him) and he said to us: O people! He who has the knowledge of any matter may convey it to the others. And he who has no knowledge, thereof, should say: "Allahu a'lam (Allah knows better)." It is a part and parcel of knowledge that a man who has no knowledge of a matter should say: "Allah knows better." Allah said to His Prophet (ﷺ):"Say (O Muhammad (ﷺ)): 'No wage do I ask of you for this (the Qur'an), nor am I one of the Mutakallifun (those who pretend and fabricate things which do not exist)."' (38:86).

The Prophet (ﷺ) said, "The deceased is tortured in his grave for bewailing over him.".

The Messenger of Allah (ﷺ) said, "He who (on befalling a calamity) slaps his cheeks, tears his clothes and follows the ways and traditions of the Days of Ignorance is none of us.".

(My father) Abu Musa got seriously ill and lost his consciousness. His head was in the lap of a woman of the family and she began to wail. When Abu Musa recovered his consciousness, he said: "I am innocent of those from whom Messenger of Allah (ﷺ) is innocent. Verily, the Messenger of Allah (ﷺ) declared himself free of (the responsibility) for a woman who wails, shaves her head and tears up her clothes.".
